PRATT & WHITNEY PROPOSES F-22A ENGINE VARIANT FOR LONG-RANGE STRIKE
Date: May 25, 2007
WEST PALM BEACH, FL -- Connecticut-based engine maker Pratt & Whitney
plans to pitch a derivative of its F-22A Raptor engine as the future
power plant
for the Air Force's nascent long-range bomber effort, the company's
president for military engines said here. "That would be it," Thomas
Farmer, president of military engines said of the company's intention
to offer a modified F119 engine for the long-range bomber program. "It
is a well-developed engine, the [service] knows the engine, they know
its history and its capability and with the evolution of [long-range]
strike, that would be Pratt & Whitney's primary offering." While the
Air Force has yet to issue an official information request to industry
on the bomber program, Farmer noted that the engine maker had already
achieved tremendous success with another F119 engine variant -- the
F135 -- designed for the Joint Strike
Fighter aircraft. With a design based largely upon the Raptor's power
plant, Farmer said the progress made in the development of the F135
proves the reliability and versatility of the engine model. Currently,
Pratt & Whitney system engineers are in the process of testing and
evaluating advanced versions of the F135 at their engine testing
facility here. When asked if the company's long-range strike offering
would be drafted more along the lines of the original F119 or the JSF-
designed F135, Farmer said the long-range strike engine variant would
be a hybrid of the two. "The F119 is the engine with the greatest
experience and history [and]
the F135 is [still] in an evolved condition, [but] we will take the
best of both worlds," he said. Noting that members of the Air Staff --
most notably Air Force Chief of Staff Gen. T. Michael Moseley -- have
expressed a keen interest in "going off-the-shelf" for technologies
associated with the 2018 version of the futuristic bomber, Farmer said
the Raptor's F119 engine is an "off-the-shelf, good-to-go [engine]
model that is in line with the thinking of the Air Force leadership
and the acquisition community." Mandated by the 2005 Quadrennial
Defense Review, Air Force officials have begun initial development
work on preliminary concepts of its new long-range bomber. The
service's three-pronged long-range strike strategy begins with a fleet-
wide modernization of the service's bomber platforms, notably the B-2,
B-1 and B-52. The second phase, outlined by senior service officials,
anticipates
fielding a midterm bomber platform within the 2018 time frame, with
the service's final long-range strike aircraft slated to hit the ramp
by 2035. Blue-suited officials have been mum over what capabilities
the service expects in the 2018 and 2035 bomber since the Air Force
was still mulling over the effort's analysis of alternatives. Air
Combat Command chief Gen. Ronald Keys stated that the program's
development would be more than likely carried out under the auspices
of a "black" or classified program. Defense observers had opined that
the possible capabilities for the 2018 aircraft include flying at
subsonic or supersonic speeds and possess unmanned operating
capabilities. However Air Force officials, citing the recently
completed AOA, have stated in recent weeks that the 2018 long-range
strike aircraft would be a manned subsonic platform. Such revelations
prompted
Pratt & Whitney's offering for the burgeoning weapons system.
