Defense - US Army completes third test of Lockheed’s Precision Strike Missile

US Army completes third test of Lockheed’s Precision Strike Missile


 and  , Defense News, April 30, 2020

WASHINGTON — The Army held a third test for Lockheed Martin’s precision strike missile, or PrSM, firing it out of a HIMARS launcher at White Sands Missile Range, in New Mexico, Thursday morning.
This latest 85-kilometer test was the shortest and most challenging yet, according to Brig. Gen. John Rafferty, the Army’s Long Range Precision Fires cross-functional team director.
“The missile almost has to start tipping over as soon as it comes out of the launcher. It has to burn off a lot of energy in order to turn over," said Rafferty. “But we started off with 240 kilometers, went to 180 and now we’re at 85.”
Future testing will look at longer ranges, and Army Futures Command is examining what officials actually want the PrSM missile to do, including engaging moving armored vehicles at extended ranges. A maximum range shot will occur in roughly one year.
The missile performed as expected and as required in every way, as it had in two previous tests, said Gaylia Campbell, Lockheed’s vice president of precision fires and combat maneuver systems.
“The team has really performed flawlessly,” Campbell said. “And being able to take a clean sheet design of a new missile and be able to perform three for three — [that’s] really 100 percent mission success. And it’s the Army’s No. 1 modernization priority.”
At this point, Lockheed is the only competitor vying to replace the Army Tactical Missile System after Raytheon exited the competition in March. Being down to one competitor might not be permanent, though, according to Gen. John Murray, who helms Army Futures Command.
“No concern whatsoever about being down to one competitor,” Murray said. "Based upon a lot of factors, there will be chances to introduce competition in this program as we get into further increments.”
Future increments, called spirals, would add a more capable seeker, make the missile more lethal and extend its range. For the missile’s seeker technology, Rafferty said his team is moving into the hands-on testing, outside of the lab, in the next few months.
Campbell said Lockheed plans to participate in any future competitions, "looking at what what are possible solutions for those next spirals.”
The request for proposals the Army put out asked for a range of 499 kilometers, but the service anticipates the final range will exceed 500 kilometers in light of the United States’ withdrawal from the Intermediate-Range Nuclear Forces Treaty.
And because the PrSM missile will be shot out of the same HIMARS launchers used by the ATACMS system it’s intended to replace, the Army expects to save money.
“We’re not investing in a new fleet of launchers and we’re getting two missiles in the same pod that our current missile goes into, so we’re actually doubling the load-out of our current fleet with this missile technology,” Murray said.
The new missile system will have applications in multiple theaters, as well, noted Rafferty.
“The early capability is against long-range artillery and integrated air defense systems,” he said. “As you integrate the seeker technology, it gives you the ability to go after the mini-targets. Those mini-targets can be maritime in the Pacific; those mini-targets can be fire control radars [and airfields] in the European scenario.”
Operating with the PrSM missile should be a smooth transition for soldiers already used to working on the ATACMS system, Rafferty and Murray said. Though there will be some changes to techniques, tactics and procedures, Army rocket crews will be using much of the same software, computers and platforms.
“Outside looking in, it looks exactly the same for our soldiers,” said Murray.

Virgin Galactic's spaceship VSS Unity landed in the New Mexico desert on Friday, marking its first glide flight from Spaceport America as the company moves toward commercial operations.

The company announced the flight on social media and shared photos of the craft on the runway and members of the crew stationed far apart around the special carrier plane that ferries the smaller spaceship to high altitude.

After years of development and testing at Mojave Air & Space Port in Mojave, California, Virgin Galactic is close to starting actual operations at its futuristic terminal and hangar in southern New Mexico. The company has not set a date for the first commercial flights but has said it anticipates doing so in 2020.

A small number of test flights are needed before Virgin Galactic can take paying customers on supersonic thrill rides to the lower reaches of space to experience a few minutes of weightlessness and a view of the Earth below. The suborbital flights will reach an altitude of at least 50 miles (80.5 kilometers) before the spaceship glides to a landing.

The company considered Friday's flight a major achievement that has been in the works since the spaceship and carrier plane relocated to New Mexico in February.

The flight provided the first opportunity to test all the components required to fly the carrier aircraft and spaceship in glide configuration from their new home base. Officials will now be reviewing data gathered during the exercise so they can prepare for the next test flight.

The spaceship reached a glide speed of Mach 0.70 as the pilots performed a series of maneuvers to check handling and aerodynamics and to get more familiar with the New Mexico airspace.

Virgin Galactic CEO George Whitesides congratulated his team on hitting the milestone, especially during such challenging times.

'I am grateful for the commitment displayed by everyone involved, not only in helping to support relief efforts in both New Mexico and California, but also for the dedication and creativity which will allow us to continue safely towards our goal of commercial launch," he said.

While many employees have been working remotely during the pandemic, members of the Virgin Galactic team have been helping with relief efforts. They've donated meals, masks, gloves and other medical supplies to communities and hospitals in New Mexico and California.

The company also has made donations of more than $60,000 in New Mexico and is working on developing oxygen hoods that could potentially help COVID-19 patients.

"We're pursuing sort of an all-hands-on-deck strategy here where we're really trying to help wherever we can," Whitesides said.

Virgin Galactic went public on the New York Stock Exchange last fall. Company officials are preparing to release their first quarter results Tuesday.

More than 600 customers from around the world have put down deposits for flights, and about 8,000 reservations of interest have been made since the successful test flight into space in December 2018. Company officials expect that interest to surpass the company's capacity for flights for the next few years.

The initial seats were sold at $250,000 apiece. Those who want to register interest online are paying a fully refundable deposit of $1,000.

Solar wind speeds seem to have stabilized back to the low end of normal, dropping as low as 275 KPS yesterday, now in the 300-325 KPS range. That said, the Phi Angle has been pretty "shifty" over the last 24 hours. The KP-Index was in the KP-1 to KP-0 range for a good portion of yesterday, but it ramped up to KP-3 just before midnight, and then ramping back down to KP-1 for the last two readings. A new bright spot has developed at about 25° South, and should cross the midpoint in about 2-3 days. I checked the Solar Visible Light animation on SWPC, and it's not showing any underlying sunspots that I could detect. Did see some magnificent magnetic prominences along the lim of the Southeast at 304Å. A rather sharp Mag 5.9 well off the Southern tip of Japan, a pair of Mag 5.1 temblors off Tonga and the Easter Island region, and a Mag 5.2 off the Izu Islands well East of Japan.

SPACE - S0 - 20200503 - Cosmic Arcs, New Resonant Cavity Solar Micronova Trigger

Good Morning, 0bservers!

   

    
Solar winds were jumpy again yesterday, and that's a bit of an understatement. It had one sudden surge to around 470 KPS, then suddenly dropped to the ambient speed of 310 KPS, then jumped again to 500 KPS for a couple hours, falling again to the 320-350 range, with a slow slope back to a current 300 KPS "breeze" This likely due to the Earth crossing the solar electromagnetic sheet, but it's odd to actually see it have such a sharp effect. Speed hikes were matched by brief spikes in temperature and drops in particle density. With all that said, the KP-Index stayed well in the calm range, mostly KP-1s with a couple of KP-2s and a brief KP-0. Some disorganized coronal holes keep trying to develop along the equator, but it is doubtful we'll see any significant output as they pass the midpoint. The large bright spot just South of the Equator is almost to the Western lim. No new bright spots seem to be coming across the surface, although the incoming lim does suggest some activity in the mid-to high Southern latitudes. And while nothing seemed visible on the LASCO C3 video, the WSA-ENLIL Prediction graphic on the SWPC Space Weather Enthusiast website showed an ejection a few hours ago. The current track shows that it will MISS the Earth, passing behind our orbit, so we should see little to no effect. As to the lithosphere, it was really "gettin' jiggy with it" over the last 24 hours. There was a Mag 5.5 just off the Southern coast of Puerto Rico, a strong Mag 6.6 in the Mediterranean Sea, about 55 miles South of Ierapetra Greece followed by aftershocks of Mag 5.4 and 5.3, a deep blot echo (about 115 miles) just outside Lampa Peru at Mag 5.7, and a Mag 5.1 just off the East Coast of Taiwan.

Space - NASA's Mars Helicopter receives its name from 17-year-old Alabama student

NASA's Mars Helicopter has officially been given a name: Ingenuity, thanks to Alabama High School student Vaneeza Rupani, 17, according to NASA.

The Tuscaloosa County student recommended the name, and her "motivation" behind choosing the name through the NASA "Name the Rover" essay contest. NASA states that the helicopter, manufactured by NASA's Jet Propulsion Laboratory, will be the first aircraft to "attempt powered flight on another planet," and is set to arrive on our solar system's red planet February 21, 2021.

"The ingenuity and brilliance of people working hard to overcome the challenges of interplanetary travel are what allow us all to experience the wonders of space exploration," Rupani said in her essay. "Ingenuity is what allows people to accomplish amazing things, and it allows us to expand our horizons to the edges of the universe."
  
Rupani's essay was 1 of 28,000 that were submitted to NASA by kindergarten to twelfth grade students stemming from each of the fifty United States. The rover that will accompany the helicopter was named by seventh-grade student Alexander Mathers, which he dubbed: Perseverance.

"Ingenuity encapsulates the values that our helicopter tech demo will showcase for everyone when it takes off next year as the first aircraft on another planet’s surface," said NASA Administrator Jim Bridenstine, who chose the name of the helicopter from the list of 28,000 essays.

 
"It took a lot of hard and ingenious work to get the helicopter ready and then placed on the rover, and there’s a lot more going to be required. I was happy we had another great name from the naming contest finalists from which I was able to select something so representative of this exciting part of our next mission to Mars," he added.

The news of the official naming by one of Alabama's own made it all the way up to one of the highest-sitting legislators in the state.

"I am proud that NASA’s Mars Helicopter will be named by Vaneeza Rupani of Northport, Alabama," said Alabama Senator Richard Shelby, according to NASA. "This is a unique privilege. Ms. Rupani’s essay on why she chose the name 'Ingenuity' highlights her creativity, originality, and intelligence. 

Her grasp on the importance of exploration is extraordinary, and I am confident that she has a bright future ahead. Congratulations to Ms. Rupani on being selected for this prestigious honor."

As per NASA, Ingenuity will accompany Perseverance to Mars, with the helicopter strapped to the rover's belly "encapsulated in a protective cover to shield it from debris during entry, descent and landing" - which will launch near Cape Canaveral Air Force Station in July or August and is planned to arrive at the red planet six to seven months later.

When NASA deems the mission a go, the four-pound solar-powered aircraft will leave its protected capsule on the rover to be tested against Mars' cold dark nights. If it survives the cold, the team intends to proceed onto flight testing the helicopter to prove if powered flight can take place on Mars, which will compile vital information for NASA engineers for their future missions to Mars. 

The aircraft has already been tested in a chamber meant to simulate the conditions on Mars at NASA's Jet Propulsion Laboratory in Southern California - they are currently undergoing "final assembly and checkout" at NASA's Kennedy Space Center in Florida.

"In the early days of this project, the feasibility of flying at Mars was questioned," said MiMi Aung, Mars Helicopter project manager at JPL, according to NASA. "But today we have a helicopter down at the launch site, installed on the rover and waiting to board the rocket which will carry us to the Red Planet. Like Vaneeza said in her essay, ingenuity and hard work led us to see beyond what was logical to what was possible. Now Ingenuity will have its chance to fly at Mars."

As per the release, the Perseverance rover mission is part of a larger plan, which includes missions to the Moon. NASA intends to send the first woman and next man to the Moon by 2024, to hopefully establish a human presence there by 2028 - eventually sending astronauts to Mars, piggybacking off of the information gathered through the upcoming Moon missions.

In search of the lighting material of the future

https://phys.org/news/2020-05-material-future.html

At the Paul Scherrer Institute PSI, researchers have gained insights into a promising material for organic light-emitting diodes (OLEDs). The substance enables high light yields and would be inexpensive to produce on a large scale—that means it is practically made for use in large-area room lighting. Researchers have been searching for such materials for a long time. The newly generated understanding will facilitate the rapid and cost-efficient development of new lighting appliances in the future. The study appears today in the journal Nature Communications.

The compound is a yellowish solid. If you dissolve it in a liquid or place a thin layer of it on an electrode and then apply an electric current, it gives off an intense green glow. The reason: The molecules absorb the energy supplied to them and gradually emit it again in the form of light. This process is called electroluminescence. Light-emitting diodes are based on this principle.

This green luminescent substance is a hot candidate for producing OLEDs, organic light-emitting diodes. For about three years now, OLEDs have been found in the displays of smartphones, for example. In the meantime, the first flexible television screens with these materials have also come onto the market.

In addition, OLEDs make cost-efficient room lighting with a large surface area possible. First, however, the materials best suited to this application need to be found. That's because many substances under consideration for OLEDs contain expensive materials such as iridium, and this impedes their application on a large scale and on extensive surfaces. Without such additives, the materials can actually emit only a small part of the energy supplied to them as light; the rest is lost, for example as vibrational energy.

The goal of current research is to find more efficient materials for cheaper and more environmentally friendly displays and large-area lighting. Here, inexpensive and readily available metals such as copper promise progress.

Under close examination

Researchers have now made a more precise examination of the copper-containing compound CuPCP. There are four copper atoms in the middle of each molecule, surrounded by carbon and phosphorus atoms. Copper is a relatively inexpensive metal, and the compound itself can be easily produced in large quantities—ideal preconditions for use over large extensive surfaces.

"We wanted to understand what the excited state of the compound looks like," says Grigory Smolentsev, a physicist in the operando spectroscopy research group. That is: How does the substance change when it absorbs energy? For example, does the structure of the molecule change? How is the charge distributed over the individual atoms after excitation? "This reveals how high the losses of energy that will not be released as light are likely to be," added Smolentsev, "and it shows us how we can possibly minimize these losses."

Using two large research facilities at PSI—the Swiss Light Source SLS and the X-ray free-electron laser SwissFEL—as well as the European Synchrotron Radiation Facility in Grenoble, France, Smolentsev and his collaborators took a closer look at the short-lived excited states of the copper compound.

The measurements confirmed that the substance is a good candidate for OLEDs due to its chemical structure. The compound's quantum chemical properties make it possible to achieve a high light yield. One reason for this is that the molecule is relatively stiff, and its 3-D structure changes only slightly when excited. Now researchers can start to further optimize this substance for use in OLEDs.

Tools for the future

What's more, the measurements at the three large research facilities at PSI and in Grenoble were significant not only for the investigation of this one copper-containing compound. There was more at stake: The experimental data obtained this way are also helpful in improving theoretical calculations regarding molecules in general. "So in the future it will be possible to better predict which compounds are more suitable for OLEDs and which less," says Grigory Smolentsev. "The measurement data will help the chemists understand which part of the molecule stands in the way of high efficiency. And of course: how the compound can be improved to increase its light output."

Solar winds stayed in the 280-330 KPS range through most of yesterday and overnight, until it suddenly spiked above 450 KPS for a couple hours before dropping back to the 330 KPS range. Particle density took a nose-dive at the exact same time. The Phi-Angle did have some perturbations, but on the surface they didn't seem that severe as to cause such a marked change. There was no corresponding surge in the KP Index, with the readings staying in the KP-1 to KP-2 range throughout most of the past 24 hours. The departing equatorial bright spot did have a release, possible a minor CME, but well past a risk to Earth. No sign of ejection on the LASCO C3. Another quiescent day in the lithosphere, with only a Mag 5.0 in Iran, and a half a dozen blot echos below that threshold.

Space - The Space Force’s next missile warning satellite is one step closer to a 2021 launch

The Space Force’s next missile warning satellite is one step closer to a 2021 launch

With thermal vacuum testing having begun April 16, the next space-based missile warning satellite has reached a major milestone, the Space and Missile Systems Center announced April 24.
The Space Based Infrared System, or SBIRS, satellites use infrared surveillance to provide global missile warning capabilities for the U.S. military. The system currently consists of four satellites in geosynchronous orbit and two active satellites in highly elliptical orbits that provide full coverage of the Earth’s surface.
Lockheed Martin was awarded a $1.86 billion contract in 2014 to produce the fifth and sixth geosynchronous SBIRS satellites, which will replace the first two in the constellation. The two new satellites are derivatives of the third and fourth geosynchronous satellites and are expected to improve overall system resiliency.
Lockheed Martin began thermal vacuum testing — which simulates the effects of the vacuum of space — on the fifth geosynchronous satellite, or GEO-5. The test cycles through hot and cold temperature ranges to ensure that the satellite will work in the harsh environment of space. According to SMC, the testing is a major milestone that drives final testing and assembly.
“TVAC testing represents the culmination of hundreds of thousands of hours of work by both the government and Lockheed Martin Space ensuring that we are giving the warfighter a national asset. I am proud of the men and women of the SBIRS program and their families for the years of sacrifice to get us to this point.” said Lt. Col. Ryan Laughton, SBIRS GEO-5/6 program manager.

SBIRS GEO-5 is expected to launch in 2021.

The fifth and sixth geosynchronous satellites will be the final additions to the SBIRS constellation. Plans for two additional geostationary satellites were scrapped in 2018 in favor of a new system — Next Gen Overhead Persistent Infrared. Next Gen OPIR will consist of three satellites in geosynchronous orbit and two covering the polar regions. Lockheed Martin was selected to build the former while Northrop Grumman was selected to build the latter. Next Gen OPIR is expected to be delivered in 2025.

Our Sun Is Surprisingly Weak Compared to Other Stars, Study Shows

MICHELLE STARR   30 APRIL 2020
https://www.sciencealert.com/the-sun-is-surprisingly-weaksauce-compared-to-other-stars

(NASA/SDO)

We're pretty familiar with our Sun. We've even sent a probe to go study it; we haven't done that with any other star. Given how closely we study it, it would be tempting to think of it as a typical example of a G-type main-sequence star, or yellow dwarf.

New research suggests that this is not the case. After conducting a survey of stars similar to the Sun, scientists have discovered that our star is unusually subdued, at least at this stage of its life.

Compared to its peers, the Sun fluctuates in brightness much less, and has much lower sunspot activity, than the average. It's a curious result - and one that could have implications for the future of our life on this planet.

We know our Sun varies a little in brightness due to its 11-year cycles. The cycle starts at a quiet period, with the solar magnetic field neatly aligned between the poles. But because the equator spins faster than the poles, it pulls the magnetic field out of shape. This results in heightened activity, sunspots, and variable brightness. Eventually - after about 11 years - the magnetic field snaps back into alignment, the poles flip and it goes back into a quiet period.

Understanding how this activity changes is a powerful tool for predicting the Sun's future. And we actually have a really powerful tool at our disposal for understanding solar activity over the past. That's Earth itself. The concentration of various elements in tree rings, ice cores and the fossil record can be interpreted to understand how the Sun has changed over time.

From these records, we know that the Sun has been more or less as active as it is now for the last 9,000 years. But far back in the distant past, it's harder to gauge whether the Sun behaved differently, and whether its current activity level is temporary.

"Compared to the entire lifespan of the Sun, 9,000 years is like the blink of an eye," said astrophysicist Timo Reinhold of the Max Planck Institute for Solar System Research (MPS) in Germany.

"After all, our star is almost 4.6 billion years old. It is conceivable that the Sun has been going through a quiet phase for thousands of years and that we therefore have a distorted picture of our star."

This is where other stars come in. We can compare the Sun to others like it to determine whether its behaviour is typical. And thanks to the Kepler space telescope, we have really detailed data. It studied a patch of sky for four years, allowing astronomers to calculate the rotation rates of tens of thousands of stars in its field of view, recording the faint dips in brightness associated with a sunspot appearing and disappearing from view.

This is key - because the rotation rate of a star is thought to contribute to the strength of the magnetic field. "The magnetic field is the driving force responsible for all fluctuations in activity," said astrophysicist Sami Solanki of MPS.

From the Kepler data, the researchers selected stars with rotation periods between 20 and 30 days. (The Sun's rotation period is 24.5 days.) They cross-referenced those stars against the data from the Gaia satellite, and identified 369 stars that are comparable to the Sun in colour, mass, composition, age, temperature and rotation rate.

(MPS/hormesdesign.de)




Then, they compared the brightness variability of those stars as recorded by Kepler against the brightness variability of the Sun. The results were clear. The Sun's fluctuations were very weak compared to most of the other stars. Typically, other stars fluctuated by five times as much as the Sun.

"We were very surprised that most of the Sun-like stars are so much more active than the Sun," said astronomer Alexander Shapiro of MPS.

But not all stars have detectable sunspots, and their rotation rates cannot be recorded. For a broader comparison, the team measured the Sun against 2,500 stars with unknown rotation rates - and in this case, the Sun seemed much more normal.

It's difficult to know precisely what this means. It could be that there are fundamental differences between stars with known and stars with unknown rotation rates. As the researchers note, it's likely that the Sun would belong to the latter group if studied at a distance by a Kepler-like telescope.

"For example, it has been proposed that the solar dynamo is in transition to a lower activity regime because of a change in the differential rotation inside the Sun," they wrote in their paper.

"According to this interpretation, the periodic stars are in the high-activity regime, whereas the stars without known periods are either also in transition or are in the low-activity regime."

Another possibility is that stars can fluctuate between activity levels, and the Sun just hasn't exhibited rowdy behaviour recently. That suggests it could do so in the future; given that a rambunctious Sun can negatively impact communications, navigation, satellites and even power grids, that's a worrying thought.

However, since the star has been relatively quiet for at least 9,000 years, the timescales for such fluctuations are probably quite long in human terms.

There's no way, at present, to tell which of these scenarios is more likely. But future observations with even more sensitive instruments could help pony up some answers.

The research has been published in Science

Happy MayDay, 0bservers!

   
    
If you were flying a solar sail ship yesterday, you were effectively becalmed as solar wind speeds stayed very low, near 260 KPS. However, an overnight Phi Angle shift bumped up the speed slightly to near 300 KPS - still in the very calm range. Almost all of yesterday had KP-0 readings, causing a brief Cosmic Ray Health Alert, but the latest reading bumped up to KP-3, which should blow away any potential cosmic ray risks. A patchy coronal hole developed in the last few hours, just North of the equator, and is just passing the midpoint as this report is posted. A few new bright spots are popping up on the surface, but no evidence yet of underlying sunspot activity. No earthquakes above Mag 5.0 yesterday, with only a moderate amount of blot echo activity, none higher than Mag 5.3.

Defense - US Navy adds stealth destroyer, new Arleigh Burke-class warship to the fleet

US Navy adds stealth destroyer, new Arleigh Burke-class warship to the fleet


By David B. Larter, Defense News, April 28, 2020

The guided-missile destroyer USS Zumwalt departs San Diego, Calif. (MC2 Natalie Byers/U.S. Navy)


WASHINGTON — The U.S. Navy took delivery of its first stealth destroyer and a new Flight IIA Arleigh Burke-class destroyer last week.
DDG-1000, the Zumwalt, is the first of a three-ship class of stealth destroyers delivered to the Navy nearly four years after it was commissioned.
The ship was delivered in two parts: the hull (mechanical and electrical delivery took place in May 2016) and the combat systems (which took place April 24, 2020).
Congress mandated in the 2017 National Defense Authorization Act that the ship not be counted in the battle force until combat systems delivery was compete.

 USS Zumwalt  leaves port on sea trials (U.S. Navy photo)


In November 2016, BAE Systems was awarded a $192 million contract to deliver the combat system for Zumwalt and its sister ship the Michael Monsoor.
The DDG-1000 program has been beleaguered by cost overruns and changes over the years. The ship’s original raison d'être, the Advanced Gun System, has been all but abandoned by the Navy as the vessel has changed from a naval gunfire support platform for landing Marines to now a surface strike platform.
As the Navy truncated the buy of Zumwalt-class destroyers from 28 ships to seven, and finally to three, the rounds for the guns became steadily more expensive, making the Long Range Land Attack Projectile too valuable to fire. The Navy has yet to identify a replacement.
Instead, the ship has been predesignated a ship killer, with Maritime Strike Tomahawk and SM-6 missiles integrated into its combat system.
The Michael Monsoor should have its combat system activation done by the second quarter of 2020, according to a Naval Sea Systems Command program brief from January. The third and final ship of the class, the Lyndon B. Johnson, is under construction at Bath Iron Works in Maine and should be delivered by December 2020.

The ship will then transit to San Diego, California, and have its combat system installed like its sister ships.
The Navy also took delivery of the Areligh Burke-class destroyer Delbert Black, DDG-119, from Huntington Ingalls Industries’ shipyard in Pascagoula, Mississippi.
Black was damaged in an accident in 2019 when a Norwegian-flagged vessel struck a barge that subsequently struck the ship, causing delays to the construction and about $31 million in damage.
Huntington Ingalls has four other destroyers under construction, including the Flight IIA destroyers Frank E. Petersen Jr. (DDG-121) and the Lenah H. Sutcliffe Higbee (DDG-123), as well as the Flight III destroyers Jack H. Lucas (DDG-125) and Ted Stevens (DDG-128).
Stevens is the first ship of a multiyear contract signed in June 2018.
