Langley AFB:

According to Lt. Col. Gregory Johnson, Deputy Chief of the JSF system management organization, the costs attached to the recent re-engineering of the F-35 Joint Strke Fighter will delay it's introduction into the US military by up to 2 years, (from 2011 to 2013).

The re-engineering of the aircraft was caused by the need to drastically reduce weight in all 3 versions, the Conventional Take Off & Landing (CTOL), the Carrier Variant (CV), and the Short Take-Off & Landing version (STOVL). Earlier this fall, Lockheed Martin managed to trim 2,700 pounds from the STOVL design, and 1,500 pounds from both the CTOL and CV versions.

Although this effort was successful it has delayed the aircraft's development schedule. Apparently undaunted however was acting Pentagon acquisition chief Michael Wynne who gave the "full steam ahead" approval on the design changes and wieght reduction implementations.

Not only did Wynne approve the updated design, he also signed off on awarding “a transition contract on an incrementally funded basis for the F136 engine in a manner consistent with preparing for system development and demonstration,”
This is noteworthy because there are 2 potential JSF engines; The Pratt & Whitney F135 engine and the General Electric F136 engine.
The F135 engine is considered "cutting edge" and consists of a 3-stage fan, a 6-stage compressor, an annual combustor, a single stage high-pressure turbine, and a 2 stage low-pressure turbine.
The F136 consists of a 3-stage fan, 5-stage compressor, a 3-stage low-pressure turbine section and a single stage high-pressure turbine.

Although Service Chief of Staff Gen. John Jumper stated at the 2004 Air and Space Technology Conference that the USAF is looking to buy the F-35 STOVL variant “in the hundreds”, ACC chief Gen. Hal Hornburg has said that the USAF will not decide on its force requirements until “well after F/A-22 IOC and as JSF comes aboard.” Those decisions will become more urgent “if any program is fundamentally delayed,” he said. “Then we’re going to have to re-look at what the other programmatics would be to keep this same net capability on the books for our AEFs.”

Bridging the technology gap:

It's important to note that each time the F-35 program calendar changes, the ACC has to consider pushing up modernization efforts on its older legacy platforms. Gen. Hornburg added that “We absolutely need this airplane”... “But as it continues to..." hit delays ... "then I have to look at: do I want to spend some of that money to modernize other airplanes like F-15Es or F-16s?”

The F-35 is not in trouble, but the delays in acquisition may very well bring about the need for updated versions of current fighter aircraft inventory.
What is intriguing about General Hornburg's statement is the question he has regarding updating the F-15 & 16's. What type of technology would help bridge the gap between the F-15/16's and the F-35?

Well, there have been test versions of both the F-15 and the F-16 that utilized vectored exhaust for substantially increased manueverability.

Could it be such aircraft might actually become operational in an effort to bridge the technology gap until the F-35 begins it's operational capability?

I do not believe that the time will be moved as far back as you have stated.



FORT WORTH, Texas , October 28, 2004 -- Initial integration testing of the Communication, Navigation and Identification (CNI) suite for the first flight of the F-35 Joint Strike Fighter has begun at Lockheed Martin’s [NYSE: LMT] Mission Systems Integration Lab (MSIL) in Fort Worth.


The initial tests of the first-flight CNI suite verified the operation of UHF and VHF communication, radar altimeter, intercom, integrated caution and warning, and identification-friend-or-foe capabilities. Over a three-week period the team tested each capability, generating early confidence in the system’s design and stability.

Assembly of the first F-35 is under way, with first flight planned for 2006.

"The F-35’s first-flight CNI system is being integrated into the Mission Systems Integration Lab and initial tests were flawless," said Bob Elrod, Lockheed Martin executive vice president and F-35 JSF program general manager. “The success of these early tests highlights the contributions and teamwork of multiple team partners, and helps to keep the F-35’s first-flight schedule on track.”

The F-35’s first-flight CNI system was designed and integrated by Northrop Grumman’s Space Technology sector, mostly using current-inventory federated systems. Northrop Grumman developed a customized interface adaptor unit to serve as the “interpreter” between these off-the-shelf components and the F-35’s displays and controls.

Hardware and software integration of the F-35’s integrated CNI suite will begin soon at Northrop Grumman’s Radio Systems lab facilities in San Diego.

The F-35 is a next-generation, supersonic, multi-role stealth aircraft designed to replace the AV-8B Harrier, A-10, F-16, F/A-18 Hornet and the United Kingdom’s Harrier GR.7 and Sea Harrier. Three F-35 variants – a conventional takeoff and landing (CTOL), a short-takeoff/vertical-landing (STOVL) and a carrier variant (CV) – each derived from a common design will ensure that the F-35 meets the performance needs of the U.S. Air Force, Marine Corps, Navy, the U.K. Royal Air Force and Royal Navy, and allied defense forces worldwide, while staying within strict affordability targets.................

Weight problems have been fixed and production on the first aircraft has continued.

I remember there were once proposals for nuclear-powered bombers with up to six parasitic fighters (much larger than the Goblin). With nucleonic (Hafnium) reactors, nuclear powered aircraft may become a practical reality once more. Unfortunately the site which hosted it, www.ufx.org... appears to be no longer in existence so I can't post anything for you folks.

However, I managed to rescue a single small image from the Google image database.



As for the F-35, I seriously am doubting whether it will ever become operational. Not with drones coming along the way they are, as well as other experimental or highly advanced black world stuff...
