Senate panel seeks end to F-22 export ban

Jim Wolf
WASHINGTON
Thu Sep 10, 2009 7:29pm EDT

WASHINGTON (Reuters) - A Senate panel urged the Air Force on Thursday to start developing an export model of its F-22 Raptor, the most advanced U.S. fighter jet, even as it voted to end U.S. purchases.

Japan, Israel and Australia have shown interest in buying the supersonic, radar-evading F-22 Raptor, designed to destroy enemy air defenses in the first days of any conflict and clear the way for other missions.

Foreign sales were banned by a 1998 law aimed at protecting the "stealth" technology and other high-tech features said to have made the F-22 too good for money to buy.

If enacted, the measure adopted by the Senate Appropriations Committee would let the Defense Department prepare a modified F-22 that protects classified and sensitive information, technologies and U.S. war fighting capabilities.

"The committee urges the Air Force to start this effort within the funds appropriated in Research, Development, Test and Evaluation, Air Force, for the F-22 aircraft," a report accompanying the bill said.

Neither Lockheed Martin nor the Air Force had any immediate comment.

Creating an export version would preserve U.S. jobs and an option to buy more F-22s later, without having to pay the full cost of restarting production.

The U.S. Air Force has estimated Japan would have to spend as much as $2.3 billion for development of its own version of the Raptor. For years, Tokyo has sought to buy two squadrons of the F-22, possibly 40 planes, a request that has become more compelling amid tensions with neighboring North Korea.

The bill, adopted 30 to 0 in 15 minutes without debate, largely backed program cuts sought by President Barack Obama. Overall, it provided $636.3 billion for defense in fiscal 2010, which starts October 1.

The measure would kill a combat search-and-rescue helicopter, a presidential helicopter and a missile-defense project called Kinetic Energy Interceptor.

It includes $128.2 billion for "overseas contingency operations," primarily to keep fighting wars in Iraq and Afghanistan.

The legislation would cap the U.S. F-22 "Raptor" fleet at 187, down from an original Air Force Cold War-era plan to buy as many as 750 of the air-superiority fighters.

Defense Secretary Robert Gates, announcing plans to terminate the F-22 on April 6, said doing so was "not a close call." He said the military should gear up more for wars such as those in Iraq and Afghanistan.

The bill, which must be reconciled with the House of Representatives' version, provided no funds for a second, interchangeable engine for the F-35 Joint Strike Fighter.

The alternate engine, which Obama considers wasteful, would be veto bait, the White House has said. In July, the House approved $560 million for the second engine development as part of its 2010 defense appropriations bill, despite the veto threat.

General Electric Co and Rolls-Royce Group PLC, partners in the second engine, have said they are confident a House-Senate conference committee will preserve competition for the F-35 engine.

Sen. Daniel Inouye, the Hawaii Democrat who chairs the appropriations committee and its defense subpanel, told reporters he did not know how the second engine's fate would play out.

"Apparently the Senate is not for it, so we'll go into conference on that basis. But as always, my mind is open," he said.

The Senate panel put rival United Technologies Corp's Pratt & Whitney unit, maker of a fully funded engine for the F-35, a step closer to a monopoly over a projected $100 billion market.

At issue is the engine and its aftermarket for three variants of the F-35, a single-engine Lockheed Martin fighter in early stages of production. It would replace at least 13 types of warplanes, initially for 11 nations.

The Senate committee, in sync with recommendations made Wednesday by its defense subpanel, broke with Obama on Boeing Co's C-17 cargo plane. It added $2.5 billion to sustain the production line by buying 10 more in 2010. The administration wants to end the C-17 program without further purchases.

The House approved $674 million in its defense appropriations bill to buy three more C-17s.

The full Senate could vote on the defense bill as early as next week. House and Senate representatives then meet to mesh their legislation before it is sent to the White House. The House-Senate conference is on track to take place by the end of this month, said Sen. Thad Cochran of Mississippi, the Senate panel's top Republican.

Why the Air Force Needs the F-22

Cancelling the F-22 Raptor, the most capable fighter plane ever produced, is yet another act in the tragedy of a nation that, bankrupting itself, embracing moral decline, and apologizing to its enemies, is losing the will to prevail. In pursuit of false prosperities that have failed even the economy, America for three presidencies and an entire generation has diminished its arsenals, unbalanced its military, and forgotten its genius for strategy.

The campaigns in the Middle East have been like a knife cutting through water, leaving behind the ineluctable infill of countries as divided, unstable, and hostile to our interests as on the day we decided to remake them in our image. Nonetheless, we have recalibrated the armed forces to deal with perhaps a division's worth of fluid irregulars worldwide, thus granting China, Russia, and Iran military holidays in which to redirect the balance of power.

Suppressing terrorism should not come at the expense of conventional forces but rather as a necessary and additional obligation to be accomplished with the left hand as the right is made stronger. The penalty for avoiding this will be Chinese military parity, Russia again a threat to Europe, a nuclear-armed Iran, and one country after another free to invade its neighbors, massacre its peoples, or launch pirates upon the sea.

Amid such static one thing stands out. As we rapidly disarm, China is just as rapidly arming. Perhaps because Americans do not play much chess we seem not to understand that a nation can be defeated without war, that after failing in the art of balance and maneuver the king may still stand, but motionlessly in check, "soft power" notwithstanding. "Soft power" in the absence of hard power is like flesh without a skeleton.

With self-destructive enthusiasm disguised as reasonableness, we now court costs of a future war (or defeat by maneuver) far greater than those of preparation or deterrence—in this economy or any other. Despite the Pacific interface with China, our fleet is smaller than at any time since 1916, and potentially halved due to China's physical control of the Panama Canal. The second President Bush built fewer ships than even his feckless predecessor. In abandoning effective missile defense and decimating the nuclear arsenal, we invite proliferation among the minor players, and, after half a century, are making a first strike by the major ones feasible once again. This year, the Air Force will keep 150 fighters in all of Europe, as at one time, while it declined but before it burned, Rome kept only a shadow of legions upon the Rhine and Danube.

In the very long list of such things is the F-22. Its stealth, speed, agility, and advanced sensors are such that in a 2006 exercise against F-15s, F-16s, and F-18s, the F-22, its pilots scarcely accustomed to it, scored 241 kills to 2. Famously, before its opponents know it's there, their aircraft are exploding. Former USAF Lt.-Col. Joseph Sussingham, F-16 Experimental Command Pilot, put it best: "To face a flight of F-22s is to face a wall of death."

The average age of Air Force fighter planes has more than doubled from 1960-1990 and is fast increasing. As the number of combat wings was nearly halved, and the U-2 and F-117 were eliminated in its anticipation, the F-22 became the keystone of American air power. With no new fighter on the horizon other than the F-35, it was as well a guarantee against placing every egg in one basket.

The original F-22 requirement for 750 aircraft has fared poorly over various administrations: G.H.W. Bush, 680; Clinton I, 442; Clinton II, 339; G.W. Bush I, 381; G.W. Bush II, 183. President Obama has inherited 186 as a result of congressional insistence, and the production lines are to be dismantled. The death of the Raptor is encompassed in the 2009 Posture Statement of the Air Force, with what irony one can imagine, that "The Department of Defense provided guidance . . . to eliminate excessive overmatch in our tactical fighter force." In a triumph of international cooperation, China, which will field its own fifth-generation fighter in 2018 or 2020, is eager to help us eliminate excessive overmatch, as are Russia and even India.

We scrapped the F-22 in favor of a single strike fighter, the F-35, for all the services. Despite major technical problems it is scandalously slated to go into production before it is fully tested. A lesser airplane, it has neither the speed, range, nor electronic capabilities of the F-22. Who needs speed? With munitions spent amidst a swarm of enemy fighters, speed allows the survival of aircraft and pilot. And the F-22's other characteristics superior to the F-35's mean that when its munitions are spent there may not even be a swarm of enemy fighters.

We have thrown away our best aircraft, as we have—directly or by attrition—discarded good ships, armor, and fighting echelons. We have closed production lines, dispersed the skilled people who run them, and weakened the defense industrial base to the point that in a national emergency it cannot revive. Even the late Sen. Edward Kennedy, hardly a hawk, called the death of the F-22 "ill-advised and premature."

Given that the administration and Congress throw panicked trillions at programs thought up in the spur of the moment, their parsimony in defence of the United States is unjustifiable, even if our brilliant elites simply refuse to contrast the supposed savings to the costs of future wars that otherwise might be prevented. Though the price may be steep for the times, the price of war undeterred, should it be lost or even should it be won, will perhaps be unbearable.

And because it is a price not only in dollars but in the life of a nation and the blood of its sons and daughters, it is necessary to speak without embarrassment for the defense of the United States and for the rightful preparation to deter war or to win it.

F-22 Raptor F119-PW-100 Engine



The F-22 incorporates a pair of new, higher thrust-to-weight engines, the Pratt & Whitney F119-PW-100, which is designed for efficient supersonic operation without afterburner (called supercruise), and with increased durability over current engines. Advanced technologies incorporated in the F119 include integrated flight-propulsion controls and two-dimensional, thrust-vectoring engine nozzles, which will give the F-22 unprecedented aircraft maneuverability. Development of the F119 was conducted at Pratt & Whitney's West Palm Beach, FL, facility, while production takes place at the company's factories in Middletown, CT. Pratt & Whitney built 27 flightworthy engines during EMD.

Designed for efficient supersonic operation without afterburner use and with increased durability over today's engines, the F119 is a very high thrust-to-weight ratio engine. Advanced technologies in the F119 include integrated flight-propulsion controls and two-dimensional, thrust-vectoring engine nozzles. The F119 incorporates technology advances developed and verified in joint U.S. Air Force/Pratt &Whitney research programs and for other advanced fighter engines. It was designed using the "integrated product development" approach to ensure a balance between performance, safety and reliability, maintainability and low life-cycle cost. In addition, it has significantly fewer and more durable components than previous fighter engines.

The F119-PW-100 is a revolutionary advance in fighter aircraft propulsion. The F119 engine develops more than twice the thrust of current engines under supersonic conditions, and more thrust without afterburner than conventional engines with afterburner.

Each F-22 will be powered by two of these 35,000-pound-thrust-class engines. By comparison, the engines powering the Air Force's current F-15 and F-16 fighters have thrust ratings ranging from 23,000 to 29,000 pounds.

Jet engines achieve additional thrust by directly injecting fuel at the engine exhaust. The process, called afterburner, gives the aircraft a rocket-like boost as the fuel ignites in the exhaust chamber. The tradeoff is higher fuel consumption, a greater amount of heat, and consequently, greater visibility to the enemy.

The F119 can push the F-22 to supersonic speeds above Mach 1.4 even without the use of afterburner, which gives the fighter a greater operating range and allows for stealthier flight operation. The product of more than 40 years' research into high-speed propulsion systems, the F119 is proof that high-technology doesn't have to be complicated.

Performance of the F119 engine has generally been excellent in testing. Full-scale airframe static testing and the first of three (originally four) planned fatigue lifetimes of testing have been completed and the second fatigue life testing is nearly complete. The program now plans to complete three fatigue lifetimes prior to the completion of the ongoing engineering and manufacturing development phase in November 2005. Expansion of flight test into the high-speed, high-G load regions of the performance envelope is ongoing.

Design

A balanced approach to the design process, using a team approach called Integrated Product Development (IPD), led to an engine as innovative in its reliability and support as in its performance. Assemblers and flight line mechanics participated in the F119's design from its inception. The result is that ease of assembly, maintenance and repair are designed into the engine.

The F119 has 40 percent fewer major parts than current fighter engines, and each part is more durable and does its job more efficiently. Computational fluid dynamics (CFD), the study of airflow using advanced computers, led to the design of engine turbomachinery of unprecedented efficiency, giving the F119 more thrust with fewer turbine stages.

The F119 cuts requirements for support equipment and labor by one-half, which also saves precious space in airlifters in combat zone deployments. The F119 will require 75 percent fewer shop visits for routine maintenance than its predecessors.

Features

• Integrally bladed rotors: In most stages, disks and blades are made from a single piece of metal for better performance and less air leakage.
  
• Long chord, shroudless fan blades: Wider, stronger fan blades eliminate the need for the shroud, a ring of metal around most jet engine fans. Both the wider blades and shroudless design contribute to engine efficiency.
  
• Low-aspect, high-stage-load compressor blades: Once again, wider blades offer greater strength and efficiency.
  
• Alloy C high-strength burn-resistant titanium compressor stators: Pratt & Whitney's innovative titanium alloy increases stator durability, allowing the engine to run hotter and faster for greater thrust and efficiency.
  
• Alloy C in augmentor and nozzle: The same heat-resistant titanium alloy protects aft components, permitting greater thrust and durability.
  
• Floatwall combustor: Thermally isolated panels of oxidation-resistant high cobalt material make the combustion chamber more durable, which helps reduce scheduled maintenance.
  
• Fourth-generation full-authority digital electronic engine control (FADEC): Dual-redundant digital engine controls - two units per engine, two computers per unit - ensure unmatched reliability in engine control systems. The same experience that introduced full-authority digital control to fighter engines works with the aircraft system to make engine and aircraft function as a single flight unit.
  
• No visible smoke: Reduces the possibility of an enemy visually detecting the F-22.
  
• Improved Supportability: All components, harnesses, and plumbing are located on the bottom of the engine for easy access, all line replaceable units (LRUs) are located one deep (units are not located on top of one another), and each LRU can be removed with just one of the six standard tools required for engine maintenance.
  

F119/F-22 Engine Nozzle

The F119 engine nozzle for the F-22 is the world's first full production vectoring nozzle, fully integrated into the aircraft/engine combination as original equipment.

The two-dimensional nozzle vectors thrust 20 degrees up and down for improved aircraft agility. This vectoring increases the roll rate of the aircraft by 50 percent and has features that contribute to the aircraft stealth requirements.

Heat-resistant components give the nozzles the durability needed to vector thrust, even in afterburner conditions.

With precision digital controls, the nozzles work like another aircraft flight control surface. Thrust vectoring is an integrated part of the F-22's flight control system, which allows for seamless integration of all components working in response to pilot commands.

The nozzle is manufactured at Pratt & Whitney's West Palm Beach facility, home to the company's military engine design and prototype construction.

Engine Assembly and Test Facilities

Pratt & Whitney's West Palm Beach, Fla., facility is the focal point for its military engine development activities. But given the Integrated Product Development process, which gives manufacture, assembly, and maintenance personnel a larger role in engine design, F119 development activities have also incorporated its eventual producers at company facilities in Middletown, East Hartford, and New Haven, Conn.; North Berwick, Me.; and Columbus, Ga.

Sea-level testing was conducted at the West Palm Beach facility. Extensive altitude testing was done at the Air Force's Arnold Engineering Development Center, Arnold AFB, Tullahoma, Tenn.

Most F119 assembly work will be conducted in Middletown, Conn., where Pratt & Whitney employs 3,000 people in the manufacture of combustors, engine cases, and major rotating parts. Middletown is a two-million square foot facility on 1,100 acres.

Components for the 26 F119 engines to be built during the current Engineering and

Manufacturing Development (EMD) phase are being produced in Middletown. At the conclusion of the proof-of-concept program, the facility and its people will have gained engine production experience and will be ready to gear up for full F119 production in support of the F-22 and Joint Strike Fighter (JSF) programs.

Components will be made by suppliers in states across the nation and at these Pratt & Whitney facilities: East Hartford, Conn.: Pratt & Whitney employs 7,800 employees in this 5.2-million square foot facility, which houses Large Commercial Engines headquarters, commercial engineering, marketing, and product support, overhaul and repair operations and manufacturing facilities. The facility specializes in single-crystal turbine blades, fans, and compressor blades, as well as commercial engine production.

• North Haven, Conn.: The 1,600 employees in this 800,000-square-foot facility make turbine and compressor blades and vanes.
  
• North Berwick, Me.: Here, 1,500 employees in an 880,000 square-foot facility manufacture blades, vanes, bearing compartments, and stators.
  
• Columbus, Ga.: The 250 employees at Pratt & Whitney's newest manufacturing plant forge disks and other engine components.
  

Schedule

In the Engineering and Manufacturing Development (EMD) phase of the program, Pratt & Whitney designed, developed, and qualified three products: 26 flight test engines, the F119 support system, and the F119 training system.

Plans call for the production of 1,000 F119 engines. This number will provide engines for the 438 planned aircraft (two per aircraft) plus sufficient spares.

F-22 Airframe Mounted Accessory Drive (AMAD)

Built by Boeing, the F-22 Airframe-Mounted Accessory Drive (AMAD) transfers shaft power from the Air Turbine Starter System (ATSS) to the F119 engines for engine starts, and from the engines to a generator and hydraulic pumps for the electrical and hydraulic systems.

The AMAD transmits power required by the high-performance F-22 throughout the flight envelope and incorporates a high-reliability lubrication system that services the AMAD-mounted generator and ATSS as well as gearbox components.

Engine Trailer

The Boeing-developed F-22 engine trailer (designated A/M32M-34) is a piece of ground support equipment that is required for installation and removal of the Pratt & Whitney F119 engines. The trailer also supports the engine for on-base towing, air, and truck shipment. For air and truck shipment a shipping adapter (a support frame that fits over the top of the engine and attaches to the trailer to secure the engine) is also required.

During engine installation, the trailer provides a six-axis (vertical, lateral, pitch, roll, and yaw) adjustment capability to precisely align the engine to the aircraft. Fine adjustments in the vertical and lateral directions are also provided for load transfer of the engine to/from the aircraft.

Once aligned, the engine slides from the trailer's rails directly to a similar set of extension rails placed in the aircraft's engine bay. From there, the engine is pushed on to the engine mounts The lower segments of two of the aircraft's engine bay frames (numbers 5 and 6) drop down to allow for engine fitting.

There are only eight connections that have to be made between the engine and the aircraft, and with the drop out links, maintainers will be able to remove and replace an engine in approximately 75 minutes.

The engine trailer is approximately 14 feet in length and 6 feet wide. When fully lowered by means of its mechanically actuated scissors lift assembly, the trailer's height is only 38 inches. Maximum height is 5 feet. The empty weight of the trailer is 3,400 pounds. The trailer's maximum payload capacity is 7,500 pounds.
