    Army’s $2.3B wish list would speed up future helo buy, boost lethality and more

    By: Jen Judson HUNTSVILLE, Ala. — The U.S. Army's $2.3 billion unfunded requirements list — or wish list — sent to Capitol Hill includes money to speed up the service's plan to buy a future long-range assault helicopter and efforts to boost lethality, such as outfitting more Stryker combat vehicles with a 30mm gun. The unfunded requirements list is something the military services send to Congress each year shortly following the release of the defense budget request to inform lawmakers on where money would be spent if there was more of it. The lists are usually provided at the request of congressional defense committees. The service has pivoted toward six modernization priorities it deems necessary to modernize the force, and through a rigorous review of every program within the Army by leadership, billions of dollars were found within its $182 billion fiscal 2020 budget to devote to the ambitious efforts within that modernization portfolio. But the Army would spend another $243 million to advance certain modernization efforts if it could, according to the wish list. For instance, if the Army had additional funds, it would want to spend $40 million to buy the XM-913 weapon system — a 50mm gun, ammunition-handling system and fire control — to outfit two next-generation combat vehicle prototypes. The NGCV is the second-highest modernization priority. The service would also want to spend $75.6 million to speed up decision-making on the future long-range assault aircraft, or FLRAA — one of the two future vertical lift lines of effort to replace the current fleet. Gen. John “Mike” Murray, Army Futures Command commander who is in charge of the service's modernization, told Defense News in a March 26 interview at the Association of the U.S. Army's Global Force Symposium that the service would like additional funding to close the gap between what it is seeing now with the two technology demonstrators, which are both flying, and a decision on the way ahead to procure FLRAA. Bell's V-280 Valor tilt-rotor aircraft has been flying for nearly two years, and the Sikorsky-Boeing team's SB-1 Defiant flew last week. The demonstrator aircraft were originally funded to help shape the service's requirements for a future vertical lift family of aircraft. The Army also wants additional funding to extend the range of the Q-53 counter-fire target acquisition radar and funding to preserve a new program for a low-Earth orbit, space-based capability to extract data and tactical imagery in denied or contested environments, something that is critical to the Long-Range Precision Fires program, the Army's top modernization priority. Lastly, additional funding would also support rapid prototyping for the next-generation squad weapon—automatic rifle. The service would want an additional $1 billion to address readiness to include $161 million in more aviation training, $118 million in bridging assets and $128 million for mobilization needs. Also included in the readiness funding: money to further enhance interoperable communications with allies and partners, and funds to help restore airfields, railheads and runways in Europe that would enhance better movement. U.S. Army Europe commanders in recent years have stressed the need to build better infrastructure to move troops and supplies more freely in the region and have cited interoperability issues with allies as one of the toughest aspects to overcome in joint operations. Funding would also be used to enhance the Army's pre-positioned stock in Europe with petroleum and medical equipment. In the Pacific area of operations, the funding would also cover needed multidomain operations capabilities and force protection for radar sites and mobile ballistic bunkers. Focusing on lethality requirements, the Army wants an additional $249 million to upgrade more Strykers with 30mm cannons. The service is already up-gunning Strykers for brigades in Europe and recently wrapped up an assessment of the enhanced Strykers to inform a decision on whether to outfit more Strykers with a larger gun. The Army is expected to make a decision within days on whether it will up-gun more Stryker units and how many it plans to upgrade. Additionally, the Army wants $130 million to prototype hypersonic missile capabilities and another $24 million to integrate the Joint Air-to-Ground Munition's seeker and guidance kit into an Army Tactical Missile System. JAGM is the service's Hellfire replacement, and ATACMS will be replaced with the service's long-range precision fire missile — the precision strike missile — currently under development. The Army is also asking for $565 billion for infrastructure improvements both in the United States and in the Indo-Pacific area of operation.

    The US Navy is seeking upgrades for the F-35 radar’s sea-search mode

    By: David B. Larter and Valerie Insinna WASHINGTON — The U.S. Navy wants more from the F-35 jet's radar, which in sea-search mode is limited to what is directly in front of the aircraft, according to documents exclusively obtained by Defense News. According to the documents, the radar, Northrop Grumman's AN/APG-81 active electronically scanned array radar, can either hone in on a sector based on a specific point on the ground, or work in what is commonly known as “snowplow mode,” which, as the name suggests, searches everything in front of the aircraft. The Navy wants to be able to scan a wider area when in sea-search mode, something that the radar is currently not set up for, according to officials who spoke to Defense News. Officials also said the problem is on track for a solution, but may not be implemented until as late as 2024 with the Block 4 upgrades, notably adding that a solution will not be in place before a full-rate production decision on the F-35 this year. Ultimately, giving the Navy what it wants will be a matter of boosting computing power and upgrading software, officials explained. The issue is listed as a category 1 deficiency, according to the documents, which further define the limitation as something that means “adequate performance [is] not attainable to accomplish the primary or alternate mission(s).” The issue dates back to 2012, according to the documents. In this scale, category 1 represents the most serious type of deficiency. It's unclear why the issue is listed as a deficiency. The system is working in accordance with design specifications, according to both the documents and a statement from a Lockheed Martin executive. “The F-35's current radar sea search function meets the enterprises' expressed required specification," said Greg Ulmer, Lockheed Martin's general manager of the company's F-35 program. “As we modernize the F-35, we are bringing enhanced search capabilities, which represent an increase from the original requirements, and we stand ready to integrate the upgrade in the future, based on customer priorities and direction.” In an interview with Defense News, the head of the Pentagon's F-35 program office, Vice Adm. Mat Winter, said the issue was being resolved by software and computing upgrades, and there would be no requirement for a new radar. “We're not mechanically scanning, we're electronically scanning,” Winter said. “And being able to accurately scan the maritime environment, it just takes increased computing power, and that's what we're doing. ... It's a software fix, and then an allocation of computing power.” Winter may be referring to a planned bundle of computer upgrades called Tech Refresh 3, where the jet will get more modern computing systems that will increase the jet's processing power and memory. According to one document obtained by Defense News, TR3 is a prerequisite for a future radar fix. Those TR3-equipped jets won't roll off the production line until 2023. Defense News submitted written questions to the Defense Department's F-35 program office concerning these and other deficiencies, but it did not respond by press time, despite multiple follow-ups over a period of months. A retired fighter pilot, who reviewed the documents for Defense News and agreed to speak on condition of anonymity, agreed with Winter's assessment that the fix was likely software-based. Early on in the F/A-18's APG-79 AESA radar, there were glitches in the operation, but software updates smoothed out the system. Fixing the APG-81 should follow a similar track as the aircraft progresses, the pilot explained. “As long as the array itself is technically sound, I suspect over time they'll be able to find ways to continue to build out capability through software updates,” the retired fighter pilot said. https://www.defensenews.com/smr/hidden-troubles-f35/2019/06/12/the-us-navy-is-seeking-upgrades-for-the-f-35-radars-sea-search-mode/
