US Navy eyes new design for next-generation destroyer
WASHINGTON — The U.S. Navy is looking to build a new generation of destroyers from a clean-sheet design, following the model of one of its most successful ship classes, the Arleigh Burke-class DDG, the service's top officer said Tuesday.
The idea, colloquially referred to in-house as DDG Next, is to build a new hull smaller than the nearly 16,000-ton Zumwalt-class destroyer but still big enough to accommodate a larger missile magazine, Adm. Michael Gilday told a virtual audience at Defense One's State of the Navy event.
“I don't want to build a monstrosity. But I need deeper magazines on ships than I have right now,” the chief of naval operations said. “I'm limited with respect to DDG Flight IIIs in terms of what additional stuff we could put on those ships. ... So the idea is to come up with the next destroyer, and that would be a new hull. The idea would be to put existing technologies on that hull and update and modernize those capabilities over time.”
The Navy is supposed to start buying the new ship in 2025, according to the service's 2020 30-year shipbuilding plan, though it's unclear how its forthcoming force structure assessment will affect those plans. In his recent speech on the Defense Department's plan for a 500-plus ship Navy, Defense Secretary Mark Esper made no mention of the future large surface combatant.
To avoid another costly failure, such as the canceled next-generation cruiser or severely truncated DDG-1000 program, the service is harkening back to its successful Arleigh Burke program, the mainstay of the Navy's surface combatant program for the past 30 years, Gilday said. Much like on the forthcoming Constellation-class frigates, the service plans to install fielded systems on the new ship and upgrade them over time.
“So think DDG-51 (that's exactly what we did): We had a new hull but we put Aegis on it,” Gilday said. “We put known systems that were reliable and were already fielded out in the fleet. That's kind of the idea. I call it DDG Next to kind of right-size it. Smaller than a Zumwalt but packing some heat nonetheless.”
The Navy estimates it would need $22 billion annually in constant year 2019 dollars to execute its old shipbuilding plan, though the Congressional Budget Office put the estimate more than 30 percent higher. A major driver in the difference between the CBO and Navy estimate was the cost of a future large surface combatant, according the Congressional Research Service.
The emergence of hypersonic missiles has been a driving factor in the Navy's desire to field a new large surface combatant since such weapons wont fit in the current vertical launch system cells on Burke-class destroyers and existing cruisers. They will, however, fit in the Virginia Payload Module being built into the Block V Virginia submarines awarded last year.

Defense Contractors Keep Most Plants Running Despite Outbreak
By Anthony Capaccio As of Wednesday, 86 sites were closed out of 10,509 locations Boeing's aircraft plant closings are one big exception The Pentagon's contractors have largely avoided widespread closings or “major impacts” so far from the coronavirus pandemic, according to a running tally compiled by its contracts management office. Of 10,509 locations tracked or monitored by the Defense Contract Management Agency, 135 had closed at some point as of Wednesday. Forty-nine of those reopened after an average of about 10 days. “These closures have generally been short-term in order to clean facilities” or to “reduce the potential exposure of employees,” agency spokesman Matthew Montgomery said in a statement. The agency doesn't track how many workers are affected, he said. And the numbers on closings don't reflect defense contractors that have cut back their operations -- or the outsized impact of Boeing Co.'s shutdowns. Boeing, the No. 2 U.S. defense contractor, has indefinitely halted assembly of the KC-46 refueling tanker and the P-8A Poseidon maritime patrol aircraft at its facilities in Washington State, the initial U.S. center of the pandemic. Last Friday, the company began a two-week shutdown of the Philadelphia-area factory where it manufactures military rotorcraft, including the Chinook CH-47 cargo helicopter and the tilt-rotor V-22 Osprey. Huntington Is Open By contrast, Huntington Ingalls Industries Inc., has had no closings to this point, according to spokeswoman Beci Brenton. With 42,000 employees, it's the sole U.S. builder of aircraft carriers and the co-contractor of Navy attack submarines and DDG-51 destroyers. Montgomery said the Defense Department “has worked closely with local and state governments to ensure that the defense industrial base is considered critical infrastructure to help minimize the impact of statewide closures.” Impacts from closings “are being seen across all sectors including but not limited to clothing and textiles, aerospace, shipbuilding, and ground vehicles,” he said. Many Pentagon contractors “are struggling to maintain a mission-ready workforce due to work site closures, personnel quarantines and state and local restrictions on movement” that can't “be resolved through remote work,” Kim Herrington, the Defense Department's pricing and contracting director, said in a memo Wednesday. To support the defense industry, the DCMA has modified about 1,400 contracts to increase the rate for “progress payments” for work completed on time from 80% to 90% of costs incurred for large businesses and from 90% of cost to 95% for small businesses. The move resulted in $3 billion being advanced to industry, according to Herrington. That's in addition to $882 million that the Air Force is providing to Chicago-based Boeing. The funds were being withheld until the company corrected or provided sufficient plans to correct numerous deficiencies with KC-46 tankers. Most of those flaws remain unresolved. Also, the Pentagon issued guidance Thursday that lets military contracting officers reimburse companies for documented payments to employees who can't work because of coronavirus facility closings or related restrictions. https://www.bloomberg.com/news/articles/2020-04-10/defense-contractors-keep-most-plants-running-despite-outbreak
