Concerned about potential heat damage to Joint Strike Fighter (JSF) wings at supersonic speeds, aircraft prime contractor Lockheed Martin asked F-135 engine developer Pratt & Whitney to cut down on the amount of exhaust leaking through nozzles in the wings, Lockheed spokesman John Kent said July 21. The initial plane and engine specifications allow for a slight amount of leakage from the closed tube nozzles located on the bottom of the wings, Kent said. But Lockheed Martin engineers felt that even that could be too much.
VISION THING: Industry, Congress and NASA continue to snipe over the direction aeronautics research is taking at the agency. Rep. Ken Calvert (R-Calif.), chairman of the House Science space and aeronautics subcommittee, complains at a hearing on the subject that repeated shifts in NASA aeronautics strategy over the past decade have left "the appearance that the agency has no clear strategic vision" for the discipline.
Lawmakers' parochial spending priorities and tightening budgets could start affecting defense programs more widely, particularly developmental efforts, as Congress moves to finalize fiscal 2007 defense appropriations.
LUH PROTEST: MD Helicopters has filed a formal protest over EADS North America's win on the Army's Light Utility Helicopter program. Now the Government Accountability Office must review the bidding and make a ruling. The company was in financial trouble prior to the competition and hoped to win the contract for 322 helicopters to solidify its future business and, perhaps, ignite commercial market interest in its NOTAR rotorless tail technology.
The Senate Appropriations Committee has agreed to fully fund the Bush administration's $2.6 billion request for the DD(X) destroyer program, but unlike their House colleagues, the Senate panel wants the money to pay for two of the multimission surface combatants.
One aspect of U.S. space power is relatively ineffective against Hezbollah rockets fired from Lebanon into Israel, and represents the challenge that big armies face in defeating much smaller forces, experts say. Information from U.S. satellites has been passed to Israel for years, but difficulty in detecting the small Hezbollah rockets lessens the overall contribution of satellites. More than a week into the fighting, which started July 11, Israel has been unable to significantly blunt the rocket attacks.

The Defense Advanced Research Projects Agency (DARPA) has cleared SpaceX's Falcon 1 launch vehicle for its next flight, following a failure investigation that pinpointed a corroded aluminum nut as the root cause behind the March 24 loss of the first Falcon 1.
Hezbollah's constant and effective missile attacks on Israel during the recent conflict will likely cause U.S. and Israeli leaders to step up efforts to deploy a defensive directed-energy weapon like the Mobile Tactical High Energy Laser (MTHEL), says Loren Thompson, defense analyst for the Lexington Institute. "In light of what has happened recently on Israel's northern border, there is likely to be a surge of interest in MTHEL and other beam-weapon approaches to tactical defense," Thompson said July 21.
ENGINE ADDITION: The U.S. Air Force is in the midst of a 30-day review of Northrop Grumman's recommendations for an engine provider for the Joint Surveillance Target Attack Radar System re-engining project. According to industry sources, only Pratt & Whitney put in a bid, prompting the Air Force to extend the competition. However, GE said at the Farnborough Air Show outside London last week that it will offer "a generic CFM56," giving the Air Force the competition it wants.
LEBANON EVACUATION: Once all U.S. Navy ships are on the scene, officials say they will have the capacity to evacuate at least 6,000 U.S. citizens per day out of Lebanon. The last ship was scheduled to arrive July 23. Defense Department officials said five more Navy ships were set to arrive. The USS Iwo Jima was scheduled to begin taking part in the operation July 22, and the USS Nashville joined the evacuation effort July 20. Disabled and other special needs U.S. citizens are being air evacuated aboard CH-53E Super Stallions (DAILY, July 19).
NEW SU-35: Sukhoi Holding Co. has unveiled the mockup of its new Su-35 single-seat fighter, which is intended to bridge the gap between series production fourth-generation Su-30s and the in-development fifth-generation fighter. A cockpit technology demonstrator with fixed-base simulator capability is being displayed this week at the Farnborough Air Show outside London. The Su-35 is the first Russian fighter with an all-glass cockpit, and also incorporates hands on throttle-and-stick (HOTAS) technology and new engines with thrust-vectoring nozzles.
The Army has awarded McDonnell Douglas Helicopter Co. of Mesa, Ariz., a $41 million increment of the company's $613 million system demonstration and development I contract for the Apache AH-64D block III helicopter, the Pentagon announced July 19. The work is scheduled to be completed by June 30, 2011. The Block III Apache will be more powerful and connect the aircraft to the Defense Department's Global Information Grid (GIG), Brig. Gen. Stephen Mundt, director of Army Aviation, said during a July 18 Pentagon briefing.
WAR SPENDING: Since 2001, Congress has appropriated $430-$432 billion to the Defense Department and other U.S. government agencies for military and diplomatic efforts for global anti-terror and counterinsurgent efforts, according to congressional investigators. At least $386-$393 billion has gone to military operations.
Orbital Sciences Corp.'s second quarter revenues rose 11 percent to $197 million in 2006 compared to $177.4 million in 2005, while the company's operating income rose 13 percent to $16.6 million, compared to $14.7 million last year.
FARNBOROUGH - Squeezed, shrunk and kept guessing about military plans and procurement, U.S. defense and aerospace urgently need a "new deal" from Washington, says Robert H. Trice, Lockheed Martin's senior vice president of business development. Trice, speaking this week at the Farnborough Air Show outside London, displayed stacks of statistics and phalanxes of percentages showing that the perception of aerospace being a prohibitively expensive drain on taxpayers is just plain wrong.
FARNBOROUGH - Sikorsky Aircraft will develop two new Black Hawk helicopter derivatives for foreign customers called the International Black Hawk and the Armed Battlehawk. "We know that with a move to a fly-by-wire model Black Hawk it becomes a bit more expensive, so we decided to take a proven Black Hawk helicopter platform, modify it and make it more affordable to the international community," Sikorsky President Jeffrey Pino said this week at the Farnborough Air Show outside London.
FARNBOROUGH - The Russian Roskosmos space agency has canceled its tender for development of a next-generation reusable piloted spacecraft, dubbed Clipper-MKA, opting instead to develop the program jointly with the European Space Agency (ESA). Roskosmos also appointed one of the bidders - Energia Corp. - as the prime contractor. Three Russian companies participated in the state tender: NPO Molniya, Khrunichev Center and Energia Corp. Energia offered a 14.5-ton winged spacecraft designed to carry up to six crewmembers.
The U.S. Air Force's combat, search and rescue (CSAR-X) helicopter program is now scheduled for a Sept. 6 Defense Acquisition Board (DAB) review, officials connected with the program say. Initially, the Air Force was scheduled to award a contract in February 2006 for the program, which could cost about $13 billion to buy the proposed 141 aircraft and a total of $25 billion including operations and maintenance through about 2030, according to industry officials. The first block of planes is expected to go operational in 2012.
UH-1Y WORK: Bell Helicopter Textron Inc. of Fort Worth, Texas, has been awarded a $137.4 million contract to provide the U.S. Navy with seven UH-1Y aircraft, one UH-1Y full flight simulator, and four composite maintenance trainers, the Defense Department said July 20. The work will be done in Hurst and Amarillo, Texas. It is expected to be finished by September 2008. The contract was awarded by the Naval Air Systems Command, Patuxent River, Md.
Reusable rockets capable of as many as 200 firings are a step closer to reality with the first U.S. test of a full-flow staged-combustion (FFSC) cryogenic engine to achieve steady-state "mainstage" operation generating full power. The Integrated Powerhead Demonstration (IPD) ground-test engine burns liquid oxygen and liquid hydrogen in pre-burners to drive its turbomachinery, generating more power there than staged combustion cycle engines. That allows lower turbine temperatures for longer life in repeated firing on a reusable system.
Senate appropriators approved multiyear funding for the F-22A Raptor but rejected incremental funding for the next lot of fighters in the fiscal 2007 defense spending bill sent out July 20 for full Senate consideration. The $453.5 billion Senate appropriations bill, more than $5 billion less than approved by the House last month, adds $1.4 billion to the Bush administration's $1.98 billion request for F-22 procurement.
