(NSI News Source Info) TORONTO, Canada - March 23, 2015: The blue-green team is gearing up for operational tests that could build momentum for the embattled F-35B Lightning II — or add more fuel to the fire of outspoken critics.

The first shipboard operational test period for the Marine Corps' short take off and vertical landing version of the Joint Strike Fighter is scheduled to take place May 18-30 aboard the amphibious assault ship Wasp. Six of the jets will participate, four out of Marine Corps Air Station Yuma, Arizona, and two from MCAS Beaufort, South Carolina.

Evaluators will assess the stealth jet's integration and operation within the full spectrum of flight and maintenance operations, as well as supply chain support while embarked at sea, said Maj. Paul Greenberg, Marine Corps spokesman. Lessons learned will "lay the groundwork" for future deployments, he said. The aims of the at-sea tests include:

*Assess day and night take-offs and landings, weapons loads, and extended range operations.
*Assess aircraft-to-ship network communications.
*Evaluate the landing signal officer's launch and recovery software.
*Test the crew's ability to conduct scheduled and unscheduled maintenance.
*Determine the suitability of maintenance support equipment for shipboard operations.
*Assess the logistics footprint of a deployed, six-plane F-35B detachment.

The F-35B remains the centerpiece of Marine fixed-wing modernization because "it supports our doctrinal form of maneuver warfare and our operational need for close air support in austere conditions and locations potentially inaccessible for traditional fighters," Greenberg told Navy Times on March 17."The Lightning II will provide effective close-air support to our Marines and sailors when they need it the most."

Twenty-one alterations were required to equip the Wasp for regular operation of the F-35B aircraft, according to Matt Leonard, spokesman for Naval Sea Systems Command. Each alteration will be made on all L-class ships during planned availabilities and in line on newly constructed ships in advance of the F-35B's arrival.

Among the biggest challenges has been the downward force and heat of the F-35B's engines as it lands, which has burned the nonskid deck. A new highly tolerant, temperature resistant thermal spray coating was applied and has been successfully evaluated aboard Wasp during F-35B, V-22, AV-8B and other helicopter flight operations, Leonard said.

The Wasp also underwent seven "cornerstone" alterations that provide necessary electrical servicing upgrades, expand weapons handling and storage, provide for the F-35B Autonomic Logistics Information System, secure access facilities, and relocate the flight deck tramline for flight safety.

The Wasp is the test ship for the F-35B and has not made a major deployment in over a decade.

While the Air Force's decision to replace the venerable A-10 with its F-35A variant has nabbed headlines, some analysts and lawmakers remain critical of the Corps' next-generation jump jet for three reasons. It has the shortest range and smallest payload of any F-35, its capabilities are reduced and it's the most expensive. An Air Force F-35A airframe and engine runs $77.7 million, as compared to $105.5 million for the F-35B, and $89.7 million for the F-35C, according to an April 2014 Congressional Research Service report. The Marine Corps also plans to buy the carrier-based F-35C.

Supporters point out that few (if any) potential adversaries can beat the fifth-generation fighter, and this design amounts to a leap ahead for reconnaissance, electronic warfare and close-air support missions

"This actually doesn't just replace the F/A-18, the AV-8 or the EA-6. It's a fundamentally different capability," Marine Commandant Gen. Joseph Dunford said in March 10 testimony before the Senate Armed Services Committee. "It's a transformational capability. It'll do everything that those three aircraft will do, but also, in terms of the information environment, it'll do a significant amount more for the Marine air-ground task force."

Initial operating capability for the F-35B is scheduled for July.

(NSI News Source Info) TORONTO, Canada - March 4, 2014: A new F-35 Lightning II fighter jet sporting a Canadian-made tail assembly took to the skies for the first time last month, according to Magellan Aerospace Corp.

The Winnipeg-built tail assembly flew on an F-35A Conventional Take Off and Landing (CTOL) variant from defence giant Lockheed Martin’s final assembly line in Fort Worth, Texas, on Feb. 26.

“Magellan delivered the horizontal tail for the aircraft that flew today in December 2012,” Scott McCrady, Magellan’s F-35 program director, said in a company release.

“Since then our annual production rates have been steadily increasing and are expected to continually increase over the next several years as the F-35 program matures.”

Mississauga, Ont.-based Magellan is under contract with BAE Systems to produce horizontal tail assemblies for the CTOL variant of the F-35 and is expected to produce more than 1,000 assemblies for the program over a 20-year period.

Magellan, under contract with engine maker Rolls-Royce, has also been producing the vane box assembly and transition duct for all of the F-35B Short Take Off and Landing (STOVL) variant of the fighter jet.

The company has also been producing “a number of composite assemblies and machined details” directly to Lockheed Martin.

The F-35A is the conventional take-off and landing (CTOL) variant of the F-35 Joint Strike Fighter (JSF) or F-35 Lightning II fighter aircraft. The single-seat, single-engine fifth-generation F-35A has been designed and is being developed by Lockheed Martin Aeronautics for the US Air Force (USAF) and allied air forces. The multi-role, supersonic, stealthy fighter aircraft is designed to undertake air defence, ground attack and reconnaissance missions.

The F-35A will replace the USAF's F-16 Fighting Falcon fighters and will supersede A-10 Thunderbolt II attack aircraft by 2028. It is also expected to replace F-15 fighters. It addition, the F-35A will complement the F-22 Raptor air superiority fighter.
Design features of the F-35 Lightening II aircraft CTOL edition

The F-35A CTOL variant of the F-35 aircraft is designed mainly as a low-visibility aircraft with air-to-ground attack and air-to-air combat capabilities. Turning agility of the aircraft is nine times the force of gravity.  

The F-35A is more affordable as its operation and support is expected to cost 40%-50% less than current-generation aircraft used by the USAF. Another affordability feature of the aircraft is that approximately 80% of its parts are common to other variants of the F-35 aircraft.

Low visibility capability allows the aircraft to defy, retort and avoid enemy threats. State-of-the-art electronic systems add to the positional awareness of the pilot. Low-radar profile helps in maintaining the aircraft's low visibility by allowing loading of weapons and fuel internally.

Due to its lower logistics footprint, the aircraft can be positioned in an easier way than the USAF's existing fighter aircraft.

Development of Lockheed Martin's fifth-generation fighter aircraft F-35A

The critical design reviews (CDR) for CTOL variant of the F-35 aircraft were conducted in February 2006. The first flight of F-35A was undertaken in December 2006. The initial production order for two F-35A aircraft was sanctioned in April 2007.

A slightly improved version of the original aircraft was flown in November 2009.
The first night flight of F-35A was carried out in January 2012. The aircraft was tested with external weapons for the first time in February that year at Edwards Air Force Base, California. First night re-fuelling mission was completed one month later in March, while the first in-flight re-fuelling mission was completed in April 2012.

Orders and delivery of the CTOL variant of the F-35

In December 2011, the Japanese Air Self-Defence Force selected the CTOL variant to replace its ageing F-4 fleet. Israel has also shown interest in buying at least 100 F-35A aircraft.

The first two production aircraft were handed over to the USAF in May 2011. Two more F-35As were delivered in September 2011. The fifth and sixth aircraft, designated as AF-12 and AF-13 respectively, were delivered to the 33d Fighter Wing at Eglin Air Force Base in October 2011.

The F-35A was initially planned to achieve initial operational capability (IOC) in March 2013. The IOC is now projected to take place in 2016.

The US Department of Defense (USDOD) has planned to acquire 1,763 F-35As by 2034.

Armaments

The F-35A is equipped with an internally-mounted GAU-22/A Equalizer gun manufactured by General Dynamics. This 25mm gun is designed for greater effectiveness against ground targets.

The aircraft's weapon station includes three external pylons on each of the two wings with a combined capacity of 6,800kg. Moreover, there are two internal bays with two pylons each with a combined payload capacity of 8,100kg.

Avionics

Northrop Grumman Electronic Systems is supplying its AN/APG-81 Active Electronically Scanned Array (AESA) radar for the aircraft. The company is also supplying the AN/AAQ-37 Distributed Aperture System (DAS) missile warning system, which is fitted with six electro-optical sensors.

An electronic warfare suite, designated as AN/ASQ-239, will be supplied by BAE Systems. Multifunction Advanced Data Link (MADL) communication system will be provided by Harris Corporation.

Performance

The 15.7m F-35A aircraft can fly at a maximum speed of 1.6 Mach. The combat radius and maximum range of the aircraft on internal fuel are 1,093km and 2,200km respectively. Maximum g-rating of F-35A is 9.0 and weapons payload capacity is 8,160kg.
Pratt & Whitney engine for the F-35A fighter aircraft

The F-35A CTOL is powered by a single F135 engine (F135-PW-100 variant) manufactured by Pratt & Whitney. The F135 is a two-spool afterburning turbofan type engine capable of producing maximum thrust of 191.3kN and intermediate thrust of 128.1kN.

The F135 engine is an enhanced version of the F119 engine which powers the F-22 Raptor. F135 measures 135m in length and has an inner diameter of 1.17m. Overall pressure ratio of the engine is 28. Internal fuel capacity is 8,382kg.

DTN News - DEFENSE NEWS: Pentagon Helps New Stealth Fighter Cheat On Key Performance Test

Defense News: DTN News - DEFENSE NEWS: Pentagon Helps New Stealth Fighter Cheat On Key Performance Test
Source: DTN News - - This article compiled by Roger Smith from reliable sources David Axe - Wired
(NSI News Source Info) TORONTO, Canada - March 7, 2012: It seemed like a promising step for America’s next stealth fighter: The F-35 Joint Strike Fighter passed a key Pentagon test of its combat capability. But it turns out that the family of jets cleared the mid-February exam only because its proctor agreed to inflate its grade. In essence, the military helped the F-35 cheat on its midterms.
The collusion between the Pentagon testing body, known as the Joint Requirements Oversight Council (JROC), and the F-35 program — first reported by Inside Defense – confirmed that the US’ most expensive warplane met previously established performance criteria. Specifically, the review was meant to show that the jet can fly as far and take off as quickly as combat commanders say they need it to.
But the review council, which includes the vice chiefs of the Army, Navy, Air Force and Marine Corps, eased the standard flying profile of the Air Force’s F-35A model — thereby giving it a range boost of 30 miles. And it tacked an additional 15m onto the required takeoff distance for the Marines’ F-35B version, which US Defense Secretary Leon Panetta just took off budgetary probation.
The grade inflation comes at a critical time for the new warplane. The military’s new five-year budgeting blueprint, also released in February, cut more than 100 existing Air Force fighters while leaving intact plans to produce nearly 2500 F-35s — essentially doubling down on the new plane despite a recent report listing13 serious design flaws. The total cost to buy and fly the full fleet of F-35s over 50 years is estimated at around $US1 trillion, once inflation is factored in, making it the costliest defence program in human history.
In fairness, it’s not unknown for capability standards, also known as “Key Performance Parameters”, to shift during a weapon’s development. But the shifts usually reflect the evolving needs of the military or some change in the operational environment, such as a likely enemy tweaking its own defence plans. In this case, the JROC gave the F-35 a pass that was apparently designed so the over-weight, over-budget, long-delayed stealth fighter could avoid yet another embarrassing scandal.
Citing earlier efforts to boost the Joint Strike Fighter’s image, defence analyst Winslow Wheeler accused the Pentagon of “putting lipstick on the pig”. That’s an apt characterization of recent moves by the Pentagon’s F-35 boosters.
Last month, the Marine Corps held a lavish ceremony marking the arrival of two F-35 training models at the main Joint Strike Fighter “schoolhouse” in Florida. “It’s a significant jump in technology,” said Marine Lt Col David Berke, who neglected to mention that the training jets were not even cleared to fly locally. That clearance came a couple of weeks later, but again with an asterisk: Only specially qualified test pilots would be permitted to fly the jets, for now.
Increasingly, it seems the F-35 only passes tests when the tests are rigged. The good news for the fighter program typically comes with buried caveats. In response to Wheeler’s criticism, Stephen O’Bryan, then a vice president for stealth-fighter contractor Lockheed Martin, insisted that “the F-35 is meeting or exceeding every single one of the Key Performance Parameters that the services have mandated”. Of course, it’s easy to ace a test when the teacher’s already decided you passed.

DTN News - LOCKHEED MARTIN DEFENSE NEWS: Lockheed - Pentagon Order For F-35s Undefinitized

Defense News: DTN News - LOCKHEED MARTIN DEFENSE NEWS: Lockheed - Pentagon Order For F-35s Undefinitized
(NSI News Source Info) TORONTO, Canada - December 10, 2011: Lockheed Martin has signed an undefinitized contract that establishes a price ceiling for the fifth low rate production lot for the F-35 Lightning II Joint Strike Fighter, company officials clarified late on Dec. 10.

The Pentagon announced earlier on Dec. 10 that it had awarded Lockheed Martin a $4 billion contract to build 30 F-35 Joint Strike Fighter aircraft for the U.S. Air Force, Navy, andMarine Corps.

"Lockheed Martin has signed an undefinitized contract that establishes the funding for Lot 5 up to the level announced by the DoD today," said Lockheed Martin spokeswoman Laurie Quincy in an email. "The final Lot 5 contract amount will not be known until we have a definitized contract sometime in 2012."

She said in a statement that the award is welcome news for the company and its F-35 suppliers.

"This … will help ensure we continue to meet production schedules outlined by the program," Quincy wrote. "This is an important first step in paving the way for full LRIP 5 production contract negotiations with our government customer."

The fixed-price-incentive contract calls for 21 F-35A conventional take off and landing (CTOL) for the Air Force, three F-35B short-take off and vertical landing (STOVL) aircraft for the Marines, and six F-35C carrier variants for the Navy.

Broken down by service, two-thirds of the value of the contract - $2.65 billion - is for the Air Force; $937 million, or 23 percent, for the Navy; and $426 million, or nearly 11 percent, for the Marine Corps.

The contract also provides for "associated ancillary mission equipment and flight test instrumentation" for the planes, and flight test instrumentation for the United Kingdom.

The contract was awarded through the Naval Air Systems Command.

The next-generation F-35 is a stealthy (radar-evading), supersonic multirole fighter designed to meet the U.S. government's requirements for a new generation of transformational weapons. The single-engine JSF will be manufactured in three versions: a conventional-takeoff-and-landing (CTOL) variant for the U.S. Air Force, an aircraft-carrier version (CV) for the U.S. Navy, and a short-takeoff/vertical landing (STOVL) version for the U.S. Marine Corps.

The cornerstone of the F-35 is affordability, achieved in large part through a very high level of common parts and systems across the three versions of the aircraft.

The F-35 is designed to replace aging fighter inventories, including U.S. Air Force A-10s and F-16s, U.S. Navy F/A-18s, U.S. Marine Corps AV-8B Harriers and F/A-18s, and United Kingdom Harrier GR.7s and Sea Harriers.
