F-35's Costs Climb Along With Concerns Fort Worth Star-Telegram | April 26, 2006 The maiden flight of the first F-35 joint strike fighter prototype is still months away, and Lockheed Martin's giant development program is already generating budget-busting headlines. Pentagon officials, in their most recent estimate of major weapons system costs, projected a $276.5 billion cost for developing the F-35 and purchasing 2,500 of the planes for the U.S. and British armed forces. That's $20 billion more than the last estimate, in January 2004, and about a $75 billion increase since the program was launched in October 2001. Skeptics in and out of government fear that it may not be the last big cost increase because the F-35 is still in its infancy and much remains to be done to develop and perfect the warplane's high-tech systems. The question that continues to loom over the F-35 program and prime contractor Lockheed Martin Aeronautics Co. is whether, unlike so many other programs including Lockheed's F-22, the JSF can be delivered without encountering major technical problems, long delays and huge cost overruns. Defense acquisition experts with the watchdog Government Accountability Office recently urged Congress to keep a tight rein on F-35 spending until Lockheed and the other contractors show that they can design and build the airplane and meet performance and cost goals. Michael Sullivan, the GAO's acquisition analyst, is concerned that the program is attempting to do too much too fast. Congress has already appropriated funding to begin work on the first seven "production" airplanes even though basic flight testing of a "production representative" airplane won't occur until 2008 at the earliest. "Our message is they still have a lot of risks in these things until they fly the airplane," Sullivan said in an interview last week. "There are technologies they're counting on that have not been tested yet." Lockheed spokesman John Smith said some of the assumptions behind the recent cost estimate and pessimistic forecasts do not "recognize lessons that the F-35 has learned from the problems of those other programs" and assumes that the same mistakes and problems will arise again. Program and Lockheed officials say the first flight of the first test aircraft will likely take place in west Fort Worth sometime between late August and early October. "I've told everyone we'll work to August [flight date], but we'll fly when we're ready," said Rear Adm. Steven Enewold, the top military official overseeing the program. "We don't want to rush to make a first flight and then have something bad happen." Enewold acknowledged in a telephone interview last week that there are many questions yet to be answered and probably some questions that aren't even known yet. But he said he is reasonably confident that the F-35 program is on track to deliver mission-capable fighters beginning in 2011. How confident? "I'm fairly comfortable through first flight and through the end of this year," Enewold said. "After that, the risks [of encountering major technical obstacles] get bigger." After recently conducted design reviews, Enewold said indications are that the contractors can successfully manufacture the critical parts and components needed for the test planes and early production aircraft, and "we're not going to have to do a bunch of scrap and rework." He said there has been "demonstrable progress in the delivery of hardware and systems" to laboratories for testing and certification. The recent Pentagon estimates attributed most of the expected cost increases to rising costs of metals and other materials and higher inflation predictions. "We're seeing 200 percent increases in aluminum, 500 percent in titanium," Enewold said. "That's a big issue." But the GAO, in reports and testimony before Congress, says the real danger of huge cost increases lies in the program's plans to begin building production airplanes before most of the flight testing is done on all three versions of the F-35. Being forced to stop production midstream to make design changes, as Sullivan says has happened in many other programs, "is a huge driver of costs." The program should wait at least another year, preferably two, Sullivan said, and complete plenty of flight tests before beginning to build the first production aircraft. "To us, it's measure twice, cut once," Sullivan said. Program and Lockheed officials as well as other experts say that would take too long and also drive up costs. "The problem with that reasoning is we don't have a half-century to field a next-generation fighter," said Loren Thompson of the Lexington Institute, a defense think tank. "Slowing down is just another way of spending money." Smith, the Lockheed spokesman, said the F-35 "possesses very high levels of technical maturity and extremely low levels of technical risk for a fighter at this stage of its development," as shown by the recent successful design review. "Much of the F-35's technical risk will be reduced before flight testing begins." Every step taken in the F-35 program, Smith said, is done with the goal of maintaining the airplane at a price U.S. and other armed forces can afford. The F-35 program, Enewold insists, is proceeding on a deliberate basis with plenty of opportunity for government officials to slow the process down and make corrections if major problems arise. "We're going to go to an acquisition review to get permission to spend production money every year until 2013," Enewold said. http://www.military.com/features/0,1...ESRC=dod-bz.nl How were they able to design and bring the P-51 into production within one year back during WW2? Why is it so expensive and take so long now? You didn't really just ask that question, did you? "If you beat your swords into plowshares, you'll be plowing for those who didn't." |

Why is it so expensive and take so long now? You didn't really just ask that question, did you? Ah maybe b/c they did not deal with highly complex technology that has thousands of ways of failing and a few critical failures of very tiny parts that don't even move can cause the plane to crash into the ground. With WWII era planes about the most complex things were the big ol' piston engines, retractable landing gear, bomb sights...etc...today a few whiz kids could probably develop a WWII era technology fighter plane better than any seen in WWII. All you need is metal workers, engine mechanics/builders, and some pretty solid aerodynamic students. If it was so easy now then the U.S. would not make everyone else's air force into target practice. "If you beat your swords into plowshares, you'll be plowing for those who didn't." |

It wasn't until the later addition of the British engine and a couple of (supporting) airframe modifications that made it great. DS |

DS Agreed, but it is interesting to note that the original Mustang, with its Allison F3R engine, only came into being as a result of the British Purchasing Commission's earlier contact with NAA and the purchase of the Harvard trainer. NAA's wish to 'break into' the fighter market was frustrated by the US Army Air Corps lack of interest in NAA's ideas on the subject and the offer of the NA-73 fitted a British need at that time. In the event, as you point out, this original design was VERY average, the main concern from the British point of view being performance above 15,000 feet - decidedly poor, although the aircraft had considerable merit at low altitude. And the rest, as we say, is history... Ricardo |

That is interesting - I had no idea that British interest is what gave the P-51 its start. The RAF bombers didn't do high altitude stuff, most of the bombing against England was dive bombing, and the Brits already had an outstanding all-around fighter in the Spitfire. What was the Ministry's concern over high altitude performance? DS |

If it was so easy now then the U.S. would not make everyone else's air force into target practice. And having a very reliable and tested British designed engine made one hell of a contribution... Complex technology, etc. are not the issue here. The real issue, the point of the debate and the article is project management philosophy. On one side is the old guard: "Defense acquisition experts with the watchdog Government Accountability Office" who want the aircraft to roll off the line fully developed. What they want, in the WWII context, is a P-51H coming off the production line from the get-go. On the other side is the "new" project management philosophy (actually very old) , now called spiral development, where you get a production version flying asap and sequentially modify it as necessary based on continuing flight test plus service experience. There are costs associated with both philosophies. Costs to make changes versus costs of keeping a large engineering team twiddling their thumbs during flight test . Politically, spiral development is much safer. You have the aircraft flying and you can point to your successes: much less chance of having the program cancelled since there are aircraft in the fleet. Sprial development was out of favor for awhile because some programs screwed the pooch and thought they could push some critical testing off to later production versions. It ended up biting them in the ass. F-22 did not ustilise spiral development, and look how long it took them to go through flight test, how much it cost the program and the taxpayers, how many aircraft were deleted as a result, and how many times the program was almost axed. Overspec'ing the initial development of a product gives every nitwit an opportunity to point fingers if things do not go perfectly. And professional politicians are not aerospace engineers, and most don't have any technical background at all. Omega's P-51 question is thus answered: they did it by getting the basic aircraft flying and in service, then making literally dozens of model and sub- model configuration changes over the next 4 years until the war was over. I.e. Spiral Development. -- Harry Andreas Engineering raconteur |

Humm, I recall seeing a GAO report (link was in this newsgroup some time ago think) where the point was exactly the opposite. GAO wanted to have spiral development and cited F-16 as a succesful example of it, while project management was pressing for a finished product. The reasons stated were in addition to reducing development risks that a large number of aircraft in US inventory are getting old, and even a minor delay in tight F-35 schedule has grave consequences for both fighter availability and maintenance costs.

So if spiral development was used we would be a few versions into the F-22 already being it would have entered service back in the early to mid 90's and in the end the overall cost per plane would be much lower as production scaled up. I'm sure the end of the Cold War had a lot to do with the delaying of the F-22 project being a lot of the prelim work had been done in the 80's when the AF voiced the need for a post F-15 air superiority fighter. Think about how glad Russia and China most be that we delayed the F-22 so long they would not have to deal with the F-22 threat for about an extra decade. In the meantime we have given Russia a lot of time to come up with their own stealth aircraft and counter-stealth technology whatever that may mean. We would also already have a large lead towards an even more advanced fighter/UCAV to enter service in the 2015-2020 time-frame. Now for the F-22 to be cost effective its going to have to be around till 2025 and later being production has jsut started and would be spread out over several years. Talk about ****ing away a grand opportunity to truly leave Russia in the dust with regard to generations ahead of them in fighter tech vs. Cold War B.S. about how much better we were. We were better but a lot of that was training being we were not flying against trained Russian pilots but shotty 3rd world air forces with a few Ruskies in the mix to add some flavor to the engagements. |
