NOTE: Some rocket fuzes designed for use
with 2.75-inch warheads can be used with the
5.0-inch warhead by using the BBU-15/B
adapter booster (fig. 2-23).

REVIEW NUMBER 3
When classified by their mode of operation, fuzes
are classified as .
At what point does the impact-firing fuze
function?
List the two types of impact firing fizes.
At what point does the mechanical time fuze
initiate the firing train?
In acceleration-deceleration fuzes, what force
causes the fuze to function ?
Name the fuze that senses, usually by electronic
means, the presence and distance of a target.
SERVICE ROCKET ASSEMBLIES
Airborne rockets, consisting of fuzes, warheads,
and motors, are combined and assembled in various

configurations to meet specific tactical requirements.
For example, a rocket assembly that consists of a
fragmentation warhead armed with a proximity fuze is
entirely unsuitable for use against an armored tank or
bunker. Likewise, the GP warhead fuzed only with the
Mk 191 base fuze is relatively ineffective against
personnel or unarmored targets. With each specific type
of target, the right combination of warhead, fuze, and
motor is assembled from the wide variety of
components available.
2.75-Inch FFAR and LSFFAR
The 2.75-inch airborne rocket (fig. 2-24) is an
effective air-to-ground weapon against most targets.
The FFAR is an air-to-air weapon. Fired in large
numbers to produce a shotgun pattern, FFARs are
carried and launched from 7- or 19-round launcher
packages. These packages are described later in this
chapter.
The LSFFAR is accurately and safely launched
from low-speed aircraft and helicopters. Because of
their spin feature, they cannot be ripple fired. LSFFARS
are fired singly from 7- or 19-round launchers that have
single-fire capability.
The 2.75-inch rockets are received through the
supply system in three configurations as follows:
1.
2.
3.
Complete rounds in 7- or 19-tube launchers, or
in wooden boxes
Rocket motors in 7-tube launchers, and the
fuze-warhead combination in separate shipping
containers
Separate components in authorized shipping
containers
Squadron ordnancemen based ashore order and
may assemble components for current operations.
Aboard ship, weapons department ordnancemen
assemble the components according to the ship’s air and
load plan. They deliver these assemblies to squadron
ordnancemen for loading onto aircraft.
For detailed information, such as authorized
assemblies, safety precautions, and restrictions, you
should refer to Airborne Rockets, NAVAIR 11-85-5.
You can find additional information in specific aircraft
loading and tactical manuals.
