New Questions Facing the F-35: A Block Buy And A Block 4
Pentagon finally backs idea of an international ‘block buy’ for F-35s
…
Lockheed Martin produced 36 of the stealthy, single-engine jets in 2014, underscoring the steep increase in rate hoped for by program overseers. The company was pitching a block buy nearly a decade ago, long before the aircraft was mature enough for widespread commitments. Kendall’s willingness to push the concept now is a welcome relief to Lockheed Martin executives who have promised to reduce the per-unit price of the F-35A—most widely sought for export—more than $10 million apiece.
Lockheed Martin F-35 Executive Vice President Lorraine Martin said in December that she expects the per-unit cost of the F-35A in 2019, in full-rate production to be $85 million in then-year dollars, or $75 million in current dollars. This includes an aircraft with the Pratt & Whitney F135 engine and all mission systems, she said.
[Pentagon procurement chief Frank] Kendall says Pratt has made strides in reducing its price, though specifics are never shared by the Pentagon or the company. Pratt claims that its pricing should be secret due to competition. It is the sole-source supplier for the F-35 engine but points to forthcoming competitions as its basis for secrecy…
As program officials focus on establishing the block buy and marching toward the F-35’s first operational debut, for the U.S. Marine Corps with the F-35B in July, questions are surfacing about the future upgrade plan for the fighter.
The Pentagon has opted to break the so-called Block 4 into increments that will be released on two-year centers starting with 4.1 in 2019. Block 4 has long been viewed as the holy grail for the F-35. Partners agreed that in it, many weapons—especially those crucial to foreign allies—would be integrated. For the U.S. Air Force, the program office will upgrade it to be a “dual capable aircraft,” meaning it can drop nuclear weapons. And for services such as the U.S. Marines interested in maximizing air-to-ground potential, the 250-lb. Small Diameter Bomb (SDB) II would add significant volume to the number of moving ground targets the aircraft can attack.
These are among the priorities agreed upon by the F-35 partners, and they are being prioritized into the increments, says a program official. Among the partner weapons being included are Norway’s Joint Strike Missile, Turkey’s -SOM–J missile, and the U.K.’s low-collateral-damage Spear. The Navy is pushing for the Joint Standoff Weapon C1, and the Marines and Air Force are eager to get the SDB II. “We will be able to accommodate all the U.S. and partner weapons in Block 4, it is just a matter of when in that period of time between 2019 and 2025 we field that capability,” Bogdan told reporters last month.
The program office is also eager to implement an open architecture in the jet, making future upgrades easier and potentially introducing competition, rather than assuming Lockheed Martin alone will manage future blocks…
