Hi all.
Does anyone know C-130 rocket assisted takeoff length?

Is it possible that it can be 30 meters (100 ft)?


Not with a loaded Herc, and the standard JATO setup.

From the Standard Aircraft Characteristics Chart for the U.S. Navy
C-130G (The same thing as a USAF C-130E, but the Navy wouldn't use the
same subtype letter, would they? )

The normal JATO fit are 8 1000-KS-14 JATO bottles, which give you
1000# thrust for 14 seconds.

Takeoff ground run, no wind, Standard Day Sea Level at 155,000# weight
(Max payload)
4125' without JATO, 3565' with HATO
Distance to clear a 50' obstacle:
5810' without JATO, 4812' with JATO.

Note that the extra thrust doesn't help the ground run very much, but
does help the initial climbout quite a bit.


Peter, what did they do to the Herc that they flew off of the
Forrestal(?) ? (without JATO at that!)


Gave it a 40 kt headwind! It should be pointed out that the data I
gave was for a 155,000# C-130G (or E, if you're USAF). The Forrestal
flights wre made by a KC-130F, which was the Marine Corps
Tanker/Transport flavor of the C-130B. The B models had the same
egnine as the later E models, but their max weight was 135,000# rather
than 155,000#.
