used with the aircraft wing store launcher assembly,
which is modified to launch a Harpoon missile. You can
attach Aero 1A adapter assemblies to increase the bomb
rack to 30-inch suspension capacity. Because of the
added Harpoon capabilities, the BRU-15/A replaces the
Aero 65A as wing suspension racks for the P-3C aircraft.
The BRU-15/A bomb rack is a modification of the
BRU-14/A bomb rack. The functional and physical
characteristics of the BRU-15/A are shown below.
The IFOBRL mechanism and associated
auxiliary unlock device are not included.
There is a safety mechanism to positively lock
the release mechanism of the bomb rack when a safety
pin is installed.
There is a cable-actuated manual release
mechanism that operates the primary release linkage
through an added manual release cable and lever.

BOMB EJECTOR RACKS
LEARNING OBJECTIVE: Identify the
purpose and use of bomb ejector racks to
include their principles of operation,
maintenance requirements, and operational
When in flight, todays high-speed fighter and
attack aircraft create a vacuum under the fuselage and
wings. If a weapon/store is released from the bomb
rack, this vacuum can prevent the weapon/store from
entering the airstream and falling to the target. If this
happens, the weapon/store may physically contact the
aircraft structure, causing serious damage to or loss of
Bomb ejector racks are different from bomb racks.
Bomb ejector racks use electrically fired impulse
cartridges to eject the weapon/store free of the bomb
racks. Bomb ejector racks eject the weapon/store from
the bomb rack with sufficient force to overcome vacuum
buildup and ensure a safe weapon/store launching
AERO 7A-5 AND AERO 7B-4 BOMB
The Aero 7A-5 and Aero 7B-4 bomb ejector racks
are mounted externally on the A-6 aircraft. All EA-6
aircraft models are equipped with an Aero 7B-4 ejector
bomb rack on the centerline station and an Aero 7A-5
bomb ejector rack on the wing stations. These bomb
ejector racks make up the aircrafts basic weapons
suspension. They are normally referred to as parent
racks. Bomb ejector racks are mounted in fairing-
enclosed pylons for aerodynamic purposes. The pylons
have removable fairings and hinged doors for easy
access to the components of the bomb ejector racks.
Aero 7A-5 Bomb Ejector Rack
The Aero 7A-5 bomb ejector rack assembly (fig.
10-11) consists of a housing that contains the following
Four pairs of tandem suspension hooks
A dual breech assembly
Mechanical linkage connecting the hook sears to
the ejector and manual release assembly
An electrical junction box connecting the aircraft
firing pulses to the breech
Two sets of adjustable sway braces
Mechanical and electrical arming units
There are four separate pairs of suspension hooks
on the Aero 7A-5 bomb ejector racktwo pairs for
14-inch suspension and two pairs for 30-inch
suspension. The suspension hooks are self-latching,
