The Eurocopter X3 technology demonstrator flew at 255 knots in level flight, an unofficial record for a helicopter, on June 7. It also reached 263 knots in a dive. “It’s no exaggeration to say that the X3 is clearly in its element at high speeds,” said Hervé Jammayrac, Eurocopter test pilot.

The Eurocopter X3 hybrid made its record-breaking speed run just 10 days before the opening of the Paris Air Show, so it was not surprising that the EADS company brought both the unique aircraft and its crew to the Le Bourget biennial event. On June 7, the X3 flew at 255 knots in level flight and 263 knots in a dive, besting the previous record set by the Sikorsky X2 in September 2010 (250 knots level and 260 knots in descent).

Lockheed Martin and the U.S. Department of Defense (DOD) reached an agreement in principle to fund the next two low-rate initial production (LRIP) lots of the F-35 Joint Strike Fighter, comprising 71 aircraft. The company and DOD jointly announced the “handshake agreement” on July 30 in advance of signing the LRIP contracts, which will provide consecutive, 4-percent reductions in the unit cost of U.S. military variants, they said. The parties said they will release cost details when the contracts are finalized.

Assembly of the first F-35 Joint Strike fighter to be produced outside the U.S. has begun in Italy. Manufacturers delivered major structural components to the new final assembly and check-out (FACO) facility at Cameri Air Base, west of Milan, where the first F-35A conventional takeoff and landing variant, designated AL-1, will be assembled for the Italian air force. The facility is operated by a joint venture between Lockheed Martin and Alenia Aermacchi.

Senior British military officials confirmed that the UK will conduct shipboard rolling vertical landing (SRVL) trials on the F-35B version of the Lockheed Martin Lightning II stealth combat jet. The SRVL technique would allow the aircraft to land at higher weights than is currently possible in the VTOL mode. The F-35B has faced weight problems, leading to concerns that it could not “bring back” to its aircraft carrier a useful weapons load that has not been expended in combat.

Although the F-35 is in much better shape now than it was a year ago, “we’re not declaring victory yet–it’s still a development program,” said Lockheed Martin v-p of F-35 program integration Steve O’Bryan at the Paris Air Show. But O’Bryan noted that the top U.S. government procurement official had recently expressed cautious optimism and declared that there are no technical showstoppers.

F-35 engine manufacturer Pratt & Whitney has started sustainment planning for the aircraft’s F135 turbofan even as F-35s continue flight-testing. “The F135 program is in an interesting place,” Bennett Croswell, Pratt & Whitney Military Engines president, said at a Paris Air Show press briefing on June 19. “We’re in all three phases of the lifecycle of the program. We are still in development; we are producing F135 engines; and now we are in sustainment as well.”

Gripen F trials aircraft 39-7

Saab CEO Håkan Buskhe revealed this week that the company is exploring the idea of an Optional Manned Gripen (OMG). While believing that manned operations will still be needed for at least the next 40 years, Buskhe also recognizes that many “dull and dangerous” missions could be performed better by an unmanned aircraft. Using an OMG for such roles rather than acquiring another type of aircraft would, in essence, halve the logistics costs. OMGs could perhaps operate in a formation under the control of piloted aircraft.

U.S. government procurement officials issued a “much improved” school report card on the management of the F-35 Lightning II stealth fighter program. Speaking to reporters after the annual conference of customer chief executives in Fort Worth, Frank Kendall, the Pentagon’s under-secretary for acquisition, technology and logistics, said there was “a remarkable change of tone” at the meeting compared with the one he attended a year ago. Lt. Gen.

Eurocopter announced today that its X3 compound helicopter demonstrator flew at 255 knots in level flight on Friday near Istres in southeast France. Also part of the unofficial speed record was a descent at 263 knots. These speeds are just a few knots higher than those the Sikorsky X2 semi-compound demonstrator attained in 2010.

Responding to a requirement of the Fiscal Year 2013 defense authorization act, U.S. military services declared their planned initial operational capability (IOC) dates for the three variants of the Lockheed Martin F-35 Joint Strike Fighter (JSF) on May 31. The legislation required the services to establish IOC dates by June 1.
