(The U-2 program is slated to be terminated by 2011, with
its mission going to satellites and a growing supply of
unmanned RQ-4 Global Hawk reconnaissance aircraft. Some
members in Congress, however, have so far delayed attempts
to retire the current model U-2S, maintaining that there
is still no system available that can replace the
capability of this aircraft.)
C-130 Hercules
Type: Military transport aircraft
Maiden flight: 1954
Introduced: 1956 (still being produced is the C-130J
Super Hercules, the newest version of the Hercules)
Still active: The over 2,300 Hercules variants built
are scattered across the inventories of the USAF, U.S.
Marines Corps, U.S. Navy, U.S. Coast Guard and the Air
National Guard -- as well as 67 foreign governments.
The USAF selected the C-130J-30 to replace its retiring
C-130E's. Approximately 168 C-130J/J-30s are planned
for the inventory.
(The only real issue with this superb - albeit,
vintage-origin workhorse - has been the cost to
maintain about 100 of the oldest aircraft in
the U.S. inventory.)
