Moscow continues to pursue a Sukhoi-based fifth-generation fighter.
After five years of effort, Russia finally found an international
partner for the development project. In 2007 India entered an agreement
to jointly develop a fifth-generation fighter based on the Sukhoi.

The Sukhoi T-50 PAK FA -- standing for Advanced Frontline Aviation
Aircraft System -- is a stealth-enabled fighter jet designed to compete
with the American Lockheed Martin F-35 Lightning Joint Strike Aircraft
and the Lockheed Martin/Boeing F-22 Raptor. Russian air force watchers
already christened it "Raptorsky," after the F-22 Raptor, with which it
is supposed to compete.

The developers describe the T-50 PAK FA as having excellent
maneuverability, supersonic cruising speed, long range and high
protective properties. PAK FA will have a takeoff weight of 20 tons,
which falls between the takeoff weight of the two American competitor
airplanes, the F-35 JSF (17.2 tons) and the F-22 (24 tons).

The new fighter -- a medium version -- will have a traditional wing
form, though the dramatic-looking reverse-delta wing of the Su-47
Berkut influenced the Russian fighter's designers.

The Russian fifth-generation fighter is supposed to make its first test
flight this year. The testing dates have been postponed from the end of
2008, as had been previously announced by Sergei Ivanov, the Russian
deputy prime minister in charge of defense production.

Some Russian spokesmen promised deployment of the T-50 in 2013, but
according to the earlier statements by Sukhoi CEO Mikhail Pogosyan, the
new Russian-Indian fifth-generation fighter might enter mass production
by 2015.

According to Russian sources, the Sukhoi T-50 PAK FA will incorporate
technology from the two experimental predecessors: the Su-47 and the
MiG Project 1.44.

The flagships of the Russian aerospace technology -- Tekhnokompleks
Scientific and Production Center, Ramenskoye Instrument Building Design
Bureau, the Instrument Building Scientific Research Institute in
Zhukovskiy, the Ural'sk Optical and Mechanical Plant in Yekaterinburg,
the Polet firm in Nizhniy Novgorod and the Central Scientific Research
Radio Engineering Institute in Moscow -- were selected to develop the
avionics suite for the fifth-generation airplane.

NPO Saturn has been determined to lead the work on the engines. The
Novosibirsk Aviation Production Association has begun construction of
the fifth-generation fighter at its renowned Komsomol'sk-on-Amure
Chkalov plant where most Sukhoi fighters are made.

However, considering the current economic recession and the track
record of delayed deadlines, the Russian fifth-generation fighter may
stay on paper for a longer time. This would give Washington and its
allies sufficient time to launch mass production of F-35s, deploy them
on American bases and fulfill orders from international customers such
as Britain, the Netherlands and Israel.

The F-35 is expected to enter service no later than 2012, while the
Russian Sukhoi T-50 PAK FA is certain to be in mass production by that
time.

The future may not be bright for the next generation of the Russian
fighter. Many Western defense experts believe Russia's
fourth-generation fighter jets cannot withstand the U.S.
stealth-enabled tandem of F-35 and F-22, which offer high
maneuverability and near invisibility to surface radars because of
advanced radar suppression equipment. Moreover, U.S.-based simulations
and tests suggest that the stealth-enabled fifth-generation F-22 and
F-35 can defeat any current aircraft, including the Raptorsky.
