  As USAF Fleet Plans Evolve, Can The F-35A Program Survive Intact?

  Steve Trimble Original estimates for costs, schedules and quantities of the Lockheed Martin F-35 upon contract award in October 2001 proved highly unreliable over the fighter program's nearly two-decade life span, but one critical number did not: 1,763. That four-digit figure represents program of record quantity for the U.S. Air Force—the F-35's largest customer by far—accounting for more than half of all projected orders by U.S. and international customers. The Navy and Marine Corps, the second- and third-largest buyers of the combat aircraft, respectively, downsized their planned F-35 fleet by 400 aircraft in 2004. But the Air Force's quantity never budged. Although the Air Force's official number remains unchanged, the F-35A is facing a new credibility test after a series of public statements made by Gen. Mike Holmes, the head of Air Combat Command (ACC). Air Force will consider UAS to replace some F-16s ACC sets 60% goal for fifth-gen mix in fighter fleet In late February, Holmes suggested that low-cost and attritable unmanned aircraft systems (UAS) might be considered by ACC as a replacement for F-16 Block 25/30 jets (also known as “pre-block F-16s”) within 5-8 years. In congressional testimony on March 12, Holmes added that ACC's goal is to achieve a fighter fleet ratio of 60% fifth-generation jets, such as F-35As and F-22s, to 40% fourth-generation aircraft, including F-15s, F-16s and A-10s. He also said a recent analysis by the Office of the Secretary of Defense recommends an even split between fourth- and fifth-generation fighters. Barring a significant increase in the Air Force's authorized force structure, both statements appear to jeopardize the mathematical possibility for the F-35A to achieve the full program of record. As fleet acquisition plans stand today, the F-35A program of record appears sound. Lockheed has delivered at least 224 F-35As to the Air Force so far. The public program of record calls for the F-35A to replace A-10s and F-16s, which currently number 281 and 1,037, respectively, according to Aviation Week and Air Force databases. In 2010, Lockheed and F-35 Joint Program Office officials also confirmed that the F-35 would replace the F-15E fleet after 2035, which currently numbers 228 aircraft. Adding the number of F-35As already delivered, the Air Force has a replacement population of 1,770 aircraft. But Holmes' statements could significantly alter the equation. The service's latest budget justification documents show about 325 of the 1,037 F-16s now in the Air Force fleet form the “pre-block” fleet that could be retired by attritable UAS instead of F-35As. Holmes' goal of a fighter fleet with a 60% share of fifth-generation jets also complicates the forecast for the F-35A. Including the F-22 fleet's 186 aircraft, as well as 234 F-15C/Ds, the Air Force today operates a total fleet of 2,190 fighters. A 60% share of the fleet results in 1,314 total fifth-generation aircraft. After subtracting the numbers of F-22s, the Air Force would have room for only 1,128 F-35As, which implies a 34% reduction from the program of record of 1,763. The head of the Air Force's F-35 Integration Office acknowledges the numerical disparity implied by Holmes' statements, but he stands by the F-35 original program of record. “The program of record for this aircraft is really long,” Brig. Gen. David Abba said on March 9, referring to the Air Force's plans to continue F-35A production into the mid-2040s. “I understand that's a natural question to ask, but I don't think anybody's ready to make that sort of a declaration.” Altering the program of record would not change the steady, downward trajectory of the F-35A's recurring unit costs. Last year, Lockheed agreed to a priced option for Lot 14 deliveries in fiscal 2022, which falls to $77.9 million. But changing the overall procurement quantity does have an impact on the program acquisition unit cost (PAUC), which calculates the average cost per aircraft, including recurring and nonrecurring costs. In the program of record, the PAUC estimate is currently $116 million each for all three versions of the F-35. Noting the forecast length of the F-35 production program, Abba recommends taking a long-term view. “I would focus less on the program of record element,” Abba said, and more on the Air Force's plans “to keep options open.” https://aviationweek.com/defense-space/usaf-fleet-plans-evolve-can-f-35a-program-survive-intact

  Inflection point: Army wrestles to strike balance between current and future capability

  WASHINGTON — The Army is at an inflection point. It's a statement its top leaders have acknowledged countless times in recent months as they have made the case to begin major investment in future capability. But to bring online state-of-the-art technology and weapons and equipment that will maintain overmatch against peer adversaries like Russia and China, the Army will need money. Lots of money. And that means, at some point soon, the Army will have to make difficult decisions on how long legacy weapon systems and planned upgrades for those capabilities can — or should — carry the service into the future. It is Army Secretary Mark Esper and Army Chief of Staff Gen. Mark Milley's goal and mandate to have a fully modernized Army that aligns with the service's multidomain operations doctrine by 2028. It logically follows that to get there, much has to happen in the 10 years between now and then. The Army wants longer-range fires, new combat vehicles and tanks, two new helicopters, highly capable autonomous vehicles and aircraft, a robust and resilient network tying together everything on the battlefield, a layered and more advanced air-and-missile defense capability and more lethal systems for warfighters. These capabilities all fall under the Army's top six modernization priorities, which the service laid out a year ago in an overarching modernization strategy. The Army then stood up Army Futures Command — a new four-star command — that will focus on rapidly bringing online modernized equipment and weapons that fit under the top six priorities. And it put a general officer in charge of a cross-functional team for each priority to advance prototypes and technology development.

  US Army discloses timelines for Block 3 Chinook

  Gareth Jennings, London Boeing is to begin development of a Block 3-standard Boeing CH/MH-47 Chinook transport and assault helicopter toward the end of the 2020s, ahead of fielding by the US Army in the late 2030s/early 2040s. The timeline was disclosed by the army's MH-47G programme manager, Lieutenant Colonel Robert Klarenbach, in a briefing presented earlier in 2018 and seen by Jane'son 1 August. According to the briefing, Block 3 technology development for both the CH-47F and MH-47G will run from about 2027 to 2040, with production immediately following. With Boeing currently engaged in the early stages of the Block 2 upgrade for the US Army's Chinook fleet (the first of three prototypes is now in final assembly, ahead of the first low-rate initial production delivery in fiscal year 2023), in May 2017 the company first touted the notion of a Block 3 upgrade to take the Chinook out to the 2060s. No details as to what a Block 3 upgrade might include were released, but Boeing at that time noted it could feature the new Future Affordable Turbine Engine (FATE), which is being provisioned for inclusion in Block 2, as well as active parallel actuator systems and torque management systems. It could also see the Chinook become optionally-piloted. “[Optionally piloted] is not a huge technology challenge with the flights controls the Chinook has – it is more a tactics, techniques, and procedures [TTP] challenge,” said Randy Rotte, Boeing's director of cargo helicopter sales and marketing. “Unlike the [US Marine Corps'] K-MAX, which carried its cargo sling-loaded, someone would need to get inside [of the unmanned Chinook] to load and unload it.” While the US Army has yet to comment on what a Block 3 Chinook might entail, Col Klarenbach's briefing slides showed two possible configurations.
