P&W fights US government criticisms of F-35 engine reliability
Pratt & Whitney’s F135 fighter engine that powers theLockheed MartinF-35 is the target of two new US government reports criticising the propulsion system’s “very poor” reliability and 61 nonconformities with P&W’s own and the Department of Defense’s (DOD) quality management procedures.
The findings by the US Government Accountability Office (GAO) and the DOD Inspector General appear less than two months before the US Marine Corps prepares to declare initial operational capability with the first F-35B squadron.
But Pratt & Whitney argues that the GAO is mischaracterizing the F135’s reliability data and the IG report’s findings about the company’s management system do not reflect the quality of the end-product.
“The engine is reliable, and we’ll continue trying to make it more reliable,” Bennett Croswell, president of P&W’s military engines business, told reporters on 27 April.
The GAO reported on 14 April, however, that a key reliability metric for the F135 – the mean flight hours between component failures – is tracking well behind a planned growth curve.
At this point in development, that curve suggests the conventional take-off and landing version of the engine should operate more than 100 flight hours between failures, the GAO says. Fleet data shows the fleet averages a failure roughly every 25h. The short take-off and vertical landing version of the engine should be averaging about 90 flight hours between failures, but averages closer to 45, the GAO says.
Croswell acknowledges the accuracy of the GAO’s numbers, but says that report does not reflect the overall picture of the F135’s reliability record.
Although mean flight hours between component failures is below expectations, two other key reliability metrics – mean flight hours between removals and full mission capability rate – is running above expected levels, Croswell says.
Moreover, P&W’s ground-based testing of the production configuration shows that version should meet current reliability targets once it enters flight operations later this year, Croswell says.
Although the IG was sharply critical of P&W’s quality management system, Croswell says the company stands by a commercially-derived programme that it has adapted for the F135

USAF to overhaul F-16 Block 40 to 50 wings
The US Department of Defense (DoD) has issued a request for information (RfI) to overhaul the wings of its Block 40 to 50 Lockheed Martin F-16 Fighting Falcon combat aircraft.
The RfI was issued on 30 April and covers 136 aircraft. Work is set to run from fiscal year (FY) 2019 through to FY 2025.
According to the solicitation, responses are required by 1400 h local time on 1 June 2015.
The US Air Force (USAF) currently operates more than 1,000 F-16C/D aircraft of Block 40/42/50/52 configurations. With initial operating capability for its F-35A Lightning II successor not due to be declared until late 2016, and full operating capability not expected to follow until around 2022, the USAF is looking to upgrade around 350 of its F-16s under a service-life extension programme (SLEP).
In early 2014 the USAF requested that FY 2015 funds earmarked for the Combat Avionics Programmed Extension Suite (CAPES) upgrade be diverted to the SLEP instead. At that time, Secretary of the USAF Deborah Lee James said that "tough [financial] choices" had to be made on sustaining the F-16 fleet.
y no le quedan mas años ahi dice claro quevan a llevar block 40 a 50 en ningun momento dicen que vayan a construi rmas aparatos para la USAF y la empresa a dicho que brindara soporte por muchos años despues de cerrada la linea
Eso lo que quiere decir es que esos F-16 BLock 40 que IBAN a retirar de la guardia nacional y que estaba esperando y mirando Colombia como que se están envolatando cada vez más...

United States declares one its helicopters to be missing in Nepal
A US Marine Corps (USMC) Bell UH-1Y Venom utility helicopter has been declared missing by the Department of Defense (DoD) after it failed to return from an aid relief flight in Nepal.
The helicopter from Marine Light Attack Helicopter Squadron 469 had six marines and two Nepalese personnel onboard when it was last seen near Charikot, approximately 70 km northeast of Katmandu, in the mid-afternoon of 12 May.
According to the DoD, the UH-1Y was flying in support of Joint Task Force 505's humanitarian assistance work in the earthquake affected areas of Nepal. "The status of those aboard is unknown," the department said in a statement, adding that a search for the helicopter is underway.
Joint Task Force 505 is leading the United States' relief efforts under the auspices of Operation 'Sahayogi Haat' which means 'Helping Hand' in Nepali. The task force has been supporting ongoing disaster relief operations with a US Air Force (USAF) Contingency Response Group, three Marine Corps UH-1Y helicopters, four Marine Corps Bell-Boeing MV-22B Osprey tilt-rotor aircraft, four USAF Boeing C-17 Globemaster aircraft, and two Marine Corps Lockheed Martin KC-130J Hercules aircraft, as well as various ground and aviation command and control capabilities since 4 May.
The US Air Force's (USAF's) Special Operations Command (AFSOC) has retired from service the last of its Lockheed Martin AC-130H Spectre gunships after more than 45 years of service, it was announced on 28 May.
A ceremony marking the departure of aircraft 69-6569 'Excalibur' from the 16th Special Operations Squadron (SOS) of the 27th Special Operations Wing (SOW) was held at Cannon Air Force Base (AFB) in New Mexico on 26 May.
As the oldest type in AFSOC's gunship arsenal of AC-130H Spectre, AC-130U Spooky, and AC-130W Dragon Spear/Stinger II platforms, the AC-130H force of eight aircraft has been gradually drawn down over the past two years. However, despite being progressively withdrawn from service, the AC-130H has still been at the forefront of AFSOC's missions in Afghanistan, Iraq, and beyond. According to the USAF, the 16th SOS has flown more than 6,500 combat sorties during 26,000 combat hours, and has been responsible for over 4,600 enemy killed in action, along with over 5,200 enemy being captured, over the past 12 years.
The essential difference between the Spectre and Spooky platforms is that, in addition to the 40 mm Bofors cannon and 105 mm M102 Howitzer carried by both aircraft, the newer Spooky is also armed with a 25 mm Gatling gun. The AC-130W is essentially an MC-130W Combat Spear that has been equipped with a palletised precision-strike package (PSP), comprising a single 30 mm Mk 44 Bushmaster cannon, precision-guided munitions, and a single medium-calibre gun.
With the AC-130H now retired, AFSOC continues to field 17 AC-130Us, operated by the 4th SOS, 5th SOS, and 19th (Training) SOS of the 1st SOW at Hurlburt Field, and 12 AC-130W platforms operated from Cannon AFB by the 16th SOS, 73rd SOS, and 551st (Training) SOS of the 27th SOW.
As part of a wider MC/HC-130 re-capitalisation programme across AFSOC, the command is to receive 32 new AC-130J Ghostrider gunships by fiscal year 2021. Work to convert the first MC-130J Commando II into an AC-130J began in July 2012, with the type's initial operating capability set for later this year. Once the AC-130J is fully fielded, AFSOC's gunship fleet will comprise 49 AC-130U and AC-130J platforms (all 12 AC-130W Dragon Spear/Stinger II platforms will revert to their original MC-130W Combat Spear configuration).
