The US Navy is eyeing a big change to its new stealth destroyers
By: David B. Larter
NATIONAL HARBOR, Md. — The U.S. Navy is considering a significant change to its new stealth destroyers, one driven by the change of mission announced in last year's budget documents, the head of the program said May 7 at the Sea-Air-Space conference.
The service has been struggling to find a use for the ship's advanced gun system — the largest of its type fielded by the service since World War II — and now is considering stripping them off the platform entirely, said Capt. Kevin Smith, the DDG-1000 program manager at Program Executive Officer Ships.
The Navy sidelined the guns after the service truncated the buy to just three ships, and after the ammunition, called the Long-Range Land-Attack Projectile, ballooned in price to more than $800,000 per round.
"The guns are in layup,” Smith said. “We're waiting for that bullet to come around that will give us the most range possible. But given that that is offensive surface strike, we're going to look at other capabilities potentially that we could use in that volume.”
The ships shifted missions from land attack to ship-hunting and -killing last year. The Navy is integrating the SM-6 missile, which has a surface-attack mode, and are integrating the maritime strike Tomahawk to fill out the new capabilities.
In April testimony, the Navy's top requirements officer, Vice Adm. William Merz, told Congress that the slow development of the Advanced Gun System was holding back the Zumwalt.
“Even at the high cost, we still weren't really getting what we had asked for,” he said. “So what we've elected to do is to separate the gun effort from the ship effort because we really got to the point where now we're holding up the ship.”
The Navy has touted the ship's excess space, weight, power and cooling as advantages the service would want throughout the ship's life. Everything from directed energy and electromagnetic rail guns to electronic warfare equipment has been floated as add-ons to the Zumwalt-class destroyers.
The Navy got in its present pickle with the 155mm/.62-caliber gun with automated magazine and handling system because the service cut the buy from 28 ships, to seven, and finally to three.
The AGS was developed specifically for the Zumwalt class, as was the LRLAP round it was intended to shoot. There was no backup plan, so when the buy went from 28 to three, the costs remained static, driving the price of the rounds through the roof.
The program itself is coming along, said Smith.
The Zumwalt is going through trials as its combat system installation wraps up; the Michael Monsoor is heading into the yards for its combat system installation; and the Lyndon B. Johnson is nearly 85 percent complete.
The remaining work on Johnson involves running cables, painting spaces and otherwise putting the finishing touches on the ship. The ship will then leave Bath, Maine, and head toward its home port of San Diego, California.
“We're going to energize high voltage in September, lighting off the generators in the spring, then we'll be going to test and activation for the [hull, mechanical and electrical systems], trials in the fall, then delivery.”

China’s WJ-700 Armed Reconnaissance Drone Completes Maiden Flight
China's new WJ-700 high-altitude, long-endurance and high-speed armed reconnaissance drone successfully completed its maiden flight earlier this week. The “rare type” drone is capable of executing both attack and reconnaissance missions in China, according to a statement the Third Academy of the state-owned arms firm China Aerospace Science and Industry Corp (CASIC) sent to the Global Times. First unveiled at Airshow China in 2018, the WJ-700 is expected to have a maximum take-off weight of 3,500 kg, with a maximum endurance of 20 hours. It is capable of performing air-to-surface precision strikes in multiple situations such as stand-off ground attacks, anti-ship, and anti-radiation attacks, the statement said, noting that it will “create a new pattern for drone combat.” China wants to begin selling the drones to domestic and international market needs in the next five to 10 years. Compared to other popular drones, the distinguishing characteristic of the WJ-700 is its large size, meaning it has an outstanding payload capacity that allows it to carry larger munitions like anti-ship missiles and stand-off weapons that enable the drone to launch attacks from outside of an enemy anti-aircraft fire coverage zone, Wei Dongxu, a Beijing-based military expert, said. Key tactical and even strategic battlefield hubs, including radar installations, warships and command centers could be targets of the WJ-700, analysts said. The WJ-700 could deliver diverse combat missions in high-threat battlefield environments with its precision combat and wide-area reconnaissance and surveillance capabilities. After completing various system-level tests and verifications, it will be officially put into combat applications, the academy said. https://www.defenseworld.net/news/28768#.YAXP_-hKiUk

NATO allies may lift target to spend 2% of output on defence - Stoltenberg
NATO allies may decide to aim to spend more on defence than their current target of 2% of national output when they meet for their next summit in Vilnius in July 2023, the chief of the alliance said on Monday.
