Quote from: Solar on February 25, 2021, 11:20:38 PMCan you say PORK?So the claim is? "The F-35 joint strike fighter program is grappling with a shortage of the jet's Pratt & Whitney F135 engine, and it could be months before the situation starts to improve, a defense official said Friday.The problem, according to the F-35 joint program office, is twofold. First, the F135 Heavy Maintenance Center at Tinker Air Force Base, Okla., has not been able to process engines through scheduled depot maintenance as quickly as projected.Second, maintainers are discovering "premature distress of rotor blade coatings" in a "small number" of engine power modules, creating more repair work and contributing to the backlog."https://www.defensenews.com/air/2021/02/12/an-engine-shortage-is-the-newest-problem-to-hit-the-f-35-enterprise/So we need an entirely new plane because the military has issues with 6 to 7% backlog repair, "POSSIBLY" in the future?These Marxist scum never cease to amuse with their dirty tricks to bankrupt the country as they line CCP pockets.
Quote from: Hoofer on March 06, 2021, 08:00:15 AMJust thinking... when was the idea of a Joint Strike Fighter ever a good one?a "Jack of all Trades is a Master of None." ...and it cost more to accommodate multiple branches of the military than just produce exactly what each one wanted, at a much cheaper cost. Interchangeable parts on a plane with so many different functions - what a joke!Yeah, they wanted to "retire" the A-10 too, other than a Drone, it can lay down more firepower for close air support than anything else, and pretty damn good at just one job! Or a B52 bomber, or AWACS, one mission, and they do it very well. Multi-purpose BS, that's bean-counter talk.
Quote from: Bronx on February 25, 2021, 10:10:11 PMWhat's wrong with the F-22.....?Now I admit I'm not an Airforce guy with that being said I thought the F-22 was the cats meow.US admits F-35 failed to replace F-16 as planned, needs new fighter jetGoing back to the drawing board again could see the ageing F-16's replaced in 2040, once they're 60 years old.The United States Air Force announced the need for a new multi-use fighter jet to replace its aging F-16 fleet, while stressing that it would not feature the same high-price tag and technological prowess of the F-35.The announcement, made by Air Force Chief of Staff General Charles Brown came as a surprise to defence analysts, given that the F-35 was pegged as the modern fifth generation aircraft that would replace the F-16.https://www.trtworld.com/magazine/us-admits-f-35-failed-to-replace-f-16-as-planned-needs-new-fighter-jet-44483
Quote from: dickfoster on March 08, 2021, 03:02:57 AMHardly a suprize. The F16 was designed from the ground up as an air superority fighter in desperation and to do one job and do it well after the F15 debacle when the brass screwed the pooch on it. The F35 was seen at the onset as a swiss army knife compromise that trys to do many jobs but none of them well. This is not the first time that our military brass has made this mistake and I doubt it will be the last. It seems they gain in grade the further up their asses they can shove their heads. The very same mistake was made with the F4 and earlier aircraft. They simply seem to lack the ability to learn from previous mistakes.

Quote from: dickfoster on March 09, 2021, 03:51:52 AMThe F15 became so big heavy and loaded down with bullshit for multiple missions it wasn't suitable as a dog fighter. F16 development was pushed by a group known as the fighter mafia in order to get a fighter that was actually suitable as a fighter and not a ground support or bomber etc etc etc. AF brass loves to piss away money on big new projects when they have perfecty suitable aircraft already in their inventory. The A10 is a perfect example. Designed and built expressly for the ground support mission its hard to cinceive of a better aircraft in the ground support role yet AF brass has constantly tried to kill it off in order to piss away taxpayer money on costly new programs like the F35 which are inherently inferior to the A10 in the ground support role. They love spending money not their own. If you told them part of the cost of their new program will come out of their retirement benifits and you'd find a group of penny pinching misers develop overnight.
Quote from: winterset on March 09, 2021, 07:33:08 AMThe F-15 was designed to be an air superiority fighter. Which is different then what you are claiming. IT was meant to be the long range interceptor and escort craft.And it has been brilliant in that role.The F-15 and F-16 were always meant for different missions. Now the F-15E which is upgraded as a strike fighter more than an air superiority fighter.The F-16 was NOT hurriedly put together as you claim. It was meant to be the light fighter for general purposes and has done rather well at that role for quite a while; as has the F-15. Now the F-22 has taken over the role of air superiority fighter from the F-15. Last I remember is that all operational F-15's were to be upgraded to the E level and used as light bombers.Though calling a craft that can haul 23,000 lbs payload a light fighter is a bit of a misnomer. Compared to the B-52 it is though.
Quote from: Solar on March 19, 2021, 04:09:48 AMThink of the F-35 as the AR-15, it is a versatile frame in which to build upon.The Lockheed Martin F-35 Lightning II was only the second operational fifth-generation combat aircraft, but it is also essentially three planes in one. In addition to the conventional take-off and landing (CTOL) variant, the F-35A; there is the F-35C, which features larger wings and more robust landing gear, making it suitable for catapult launches and fly-in arrestments aboard naval aircraft carriers.Then there is the F-35B, which is similar in size to the F-35A variant. However, the F-35B sacrifices about a third of its fuel volume to accommodate its shaft-driven lift fan (SDLF), which allows it to land vertically like a helicopter and take-off from very short runways. The system, which was developed by Rolls-Royce, is a descendant of the Pegasus engine 11-61/F402-RR-408, the most powerful version which is used in the Harrier AV-8B.The system is comprised of a Rolls-Royce LiftFan, Driveshaft, 3 Bearing Swivel Module (3BSM) and Roll Posts. The LiftFan is capable of delivering 20,000lbf cold thrust and has a 50-inch diameter 2-stage counter-rotating fan that features a thrust vectoring variable area vane box nozzle. In vertical flight (lift-off and landing), the LiftFan produces 29,000 shaft horsepower and is capable of a 95-degree rotation in just 2.5 seconds. For lateral stability and roll control, bypass air from the engine is then used in a roll-post nozzle from each wing; while for pitch control, the areas of the exhaust nozzle and LiftFan inlet are varied while keeping the total lift constant. In 2001, the complete system, known as the Integrated Lift Fan Propulsion System (ILFPS), was awarded the Collier Trophy in 2001.The ILFPS allows the F-35B to operate from austere or short-field bases as well as a range of air-capable ships near front-line combat zones. It can still take off and land conventionally from longer runways. A downside of this capability is that the LiftSystem components are essentially dead weight during flight and as a result, the aircraft has a smaller internal weapons bay and also carries less internal fuel. However, the F-35B uses the probe-and-drogue method for aerial refueling.The Lockheed Martin-manufactured multirole fighter features low observable stealth while its active electronically scanned array (AESA) radar technology, and the ability to carry weapons internally enables the F-35B to engage ground targets at long ranges. It has a top speed of Mach 1.6 or 1,200 mph (1.6 times the speed of sound). It has a maximum thrust in excess of 40,000 pounds and an operational range of 900 nautical miles. The F-35B has a max 7G rating.It features two bays for air missiles and an additional two bays for bombs up to 450kg, while it is also armed with an external 25mm cannon.The F-35B is replacing the AV-8B Harrier IIs in the Marine Corps inventory, and the new aircraft are being stationed at the first operational F-35B base, Marine Corps Air Station Yuma, Arizona; whilst Marine Corps Air Station Beaufort, South Carolina is where F-35B training is currently taking place.https://www.19fortyfive.com/2021/03/what-makes-the-f-35b-stealth-fighter-so-special/
Quote from: dickfoster on March 09, 2021, 11:10:01 AMWhen the F15 program started it began as a figher but ended up being shoved into multiple roles so it gained weight and size till it became a sorry assed excuse for a fighter which is why the fighter mafia pushed for the F16 to be developed and to practice KISS (keep it simple stupid) and keep it a fighter. In engineering it called mission or feature creep so by the time you get to the end you have nothing like the product you started out to design and build. Generals are not design engineers nor are many of them endowed with much common in the way of common sense so when it comes to aircraft design they should all be told to sit down and STFU. Actually most of them are politicans more than any thing else so in the end you've got a lot of politicians real ones and some in uniform deciding what and how to build airplanes. And we all know how that works out.
