.1 What is the purpose of the
following:
A. Search Stores
Search stores are those deployable stores that are used in searching for and localizing a submarine target. This particular family of devices consists of compact electronic receiver/transmitters that are dropped from the aircraft into the ocean at a predetermined point. The devices receive the sounds in the ocean and transmit them to the aircraft. The on-board processor converts and displays the sound energy at the acoustic operator's station.
Search stores are usually sonobuoys which
are described by the reference material. Sonobuoys are both "active" and
"passive." Active buoys are basically mini-sonars which "ping" for submarines
are transmit the information up to the aircraft. Passive buoys are essentially
an underwater microphone (hydrophone) which passively listen to all sounds in
the water. Sonobuoys are preset and loaded into the underside of the rear
fuselage of the aircraft. More are carried internally and can be launched out of
the three pressurized chutes or the free fall chute.
B. Kill stores
Kill stores consists of torpedoes, mines, bombs, rockets and guided missiles
The primary kill store against a
submarine is the ASW homing torpedo. The primary kill store against warships is
the Harpoon anti-ship missile. Mines may be deployed in choke points (narrow
strips of water such as the straits of Gibraltar or the Hormuz Straits) against
submarines or surface ships or aircraft may be used to mine other areas such as
harbors.
.2 Define the following acronyms
associated with ordnance:
A. AGM- Air to ground missile
The P- 3 utilizes three types of AGM
missiles. The AGM-84D Harpoon missile, in which it can carry up to six missiles
externally, the AGM-65F Maverick, in which it can carry up to 4 missiles
externally and up to 4 AGM-84H/K, SLAMER missiles.
B. ATM- Air Launched training missile
C. CATM- Captive air training missile
CATMs are used for pilot training in
aerial target acquisition and aircraft controls/displays. They have both
tactical and training components.
.3 What is the purpose of the
following?
A. MK 20 (Rockeye)
Currently in use: CBU-99/CBU-100. Cluster
bombs are dispensers which contain a number of bomblets for use against armored
vehicles, personnel or small craft. Maximum Qty: 10
B. BDU-45 (572lb practice bomb)
The BDU-45 is an inert, full scale practice bomb. Full scale practice bombs are representative of service bombs in size and weight. Maximum Qty: 10
*Note: MK-82 Also noted as a practice
bomb with a max Qty of 10.
C. MK 80 series (Depth bombs)
MK-80 series are Low Drag General Purpose
bombs used in the majority of bombing operations where maximum blast and
explosive effects are desired. These bombs are designed to be aerodynamically
streamlined.
.4 What types of air-laid mines are utilized by the P-3 aircraft?
The P-3 can carry the following air-laid mines:
MK-52 Maximim Qty of 8
MK-56 Maxmum Qty of 6
MK-62 Maximum Qty of 10
MK-63 Maximum Qty of 8
MK-65 Maixmum Qty of 6
.5 State the purpose of the following
missiles:
A. AGM-84D Harpoon
The Harpoon cruise missile is an all
weather anti-ship attack weapon.
B. AGM-65F Maverick
Is a laser guided, rocket propelled,
air-to-ground missile used against fortified ground installations, armored
vehicles or surface combatants
C. AGM-84E SLAM
The Stand-off Land Attack Missile is a
cruise missile like the Harpoon except it is designed for use against land
targets. The P-3 no longer employs the AGM-84E SLAM. The current missile is the AGM-84H/K SLAMER. The purpose is the same, but with Extended Range (ER).
.6 What Two types of torpedoes are utilized by the P-3 aircraft?
The MK-46 max quantity up to 8. MK 54 with a max quatity up to 7, and the MK-50 with a max Qty of up to 6.
.7 What are the three basic types of sonobuoys?
Passive, active and special purpose.
Passive buoys are essentially an underwater microphone (hydrophone) which
passively listen to all sounds in the water. Active buoys are basically mini-
sonars which "ping" for submarines and transmit the information up to the
aircraft. Examples of special purpose buoys are the BT (bathythermograph) buoy
which measures the ocean temperature from the surface to 1,000 feet deep, the
Ambient Noise buoy which measures in decibels, the level of ambient noise in
that area of the ocean in which it is dropped.
.8 What is the purpose of a MK 64/ 84 Signal Underwater Sound (SUS) device?
The MK-84 is a sea water activated
signaling device used to communicate with a submerged submarine during
exercises. The SUS produces one of five electroacoustical codes recognizable
from short to medium range by the subs sonar.
.9 What are three types of deployable countermeasures?
(1) Chaff to create radar decoys or to
confuse radar seekers. (2) Flares to decoy heat seeking missiles. (3) Jammers to
interfere with or "jam" radars
.10 What is a pyrotechnic device?
A pyrotechnics are fireworks adapted to
military use. They are devices which produce their effects by burning and are
consumed in the process. Specifically, the military uses these items to produce
bright lights or smoke for signaling.
.11 What are the two types of marine locations markers?
MK-25 and MK-58 marine markers which are
dropped by the aircraft to provide visual marks on the oceans surface. These may
be used to mark the position of a submarine during an ASW mission or a survivor
in the water during SAR missions. The MK-25 will last from 10 to 20 minutes. The
MK-58 will last from, 45 to 55 minutes.
.12 State the purpose of the
following:
A. Bomb rack
Aircraft bombs, torpedoes, mines, missile
and other stores are suspended internally or externally from pylons by bomb
racks. Bomb racks carry, arm and release stores.
B. Pylon
a pylon is used to suspend launchers or
bombs from the aircraft wings, fuselage or bomb bay.
C. LAU-117 missile launcher
Is used to mount the AGM-65F Maverick
Missile onto the P-3
D. Sonobuoy Launch Tubes (SLTs)
These are the 48 tubes visible in the
bottom of the fuselage towards the aft end of the aircraft in which sonobuoys
are externally loaded and launched.
E. Pressurized Sonobuoy Launch Tubes (PSLTs)
These are the 3 pressurized tubes in
which sonobuoys are loaded and launched from inside the aircraft.
