AIM-54 Phoenix
The AIM-54 Phoenix Long-range air-to-air missile, carried
in clusters of up to six missiles on the F-14 Tomcat. The Phoenix missile
is the Navy's only long-range air-to-air missile. It is an airborne weapons
control system with multiple-target handling capabilities, used to kill
multiple air targets with conventional warheads. The weapon system consists
of an AIM-54 guided missile, interface system, and a launch aircraft with
an AN/AWG-9 weapon control system. The AIM-54 is a radar-guided, air-to-air,
long-range missile consisting of a guidance, armament, propulsion, and
control section, interconnecting cables, wings and fins. The total weapon
system has the capability to launch as many as six AIM-54 missiles simultaneously
from the F-14 aircraft against an equal number of targets in all weather
and heavy jamming environments.
The AIM-54 Phoenix Missile was developed in the 1970s as
the principle long-range, air-to-air, defense armament of the F-14 Aircraft.
The AIM-54 Phoenix Missile is a fielded weapon currently in Phase III,
the Production, Fielding/Deployment, and Operational Support Phase of the
Weapon System Acquisition Process.
The three versions of the AIM-54 Phoenix Missile currently
being used are the AIM-54A, AIM-54C, and the AIM-54 ECCM/Sealed. The AIM-54
is a radar-guided, air-to-air, long-range missile consisting of a guidance,
armament, propulsion, and control section, interconnecting cables, wings
and fins. The AIM-54A was the original version to become operational. The
improved Phoenix, the AIM-54C, can better counter projected threats from
tactical aircraft and cruise missiles. The AIM-54C (sealed) missile is
the most recent version and contains improved electronic counter-countermeasure
capabilities and does not require coolant conditioning during captive flight.
The AIM-54C and AIM-54C (sealed) contains built-in self test and additional
missile on-aircraft test capability. The AIM-54C missile has also been
designed for greater reliability, longer serviceable in-service time, and
a 15 percent reduction in parts.
Initial Operating Capability was attained in 1974 for the
AIM-54A, 1986 for the AIM-54C, and 1988 for the AIM-54C ECCM/Sealed. The
AIM-54C and AIM-54C ECCM/Sealed are replacing the AIM-54A. As AIM-54A inventories
are depleted they will not be replenished. The AIM-54A Technical Evaluation
(TECHEVAL) was completed in November 1973. Operational Evaluation (OPEVAL)
was completed in November 1974. The AIM-54C TECHEVAL began in May 1982
and was completed in November 1982. The OPEVAL began in March 1983 and
was completed in August 1983. AIM-54C ECCM/Sealed Missile TECHEVAL was
completed in June 1985, and OPEVAL was completed in July 1988.
The AIM-54 Phoenix Missile, used exclusively on the F-14A/B/D Aircraft,
is a radar guided, air-to-air missile consisting of a guidance section,
armament section, propulsion section, control section, interconnecting
surface cables, wings, and fins. The missile is designed for ejection launch
using the LAU-93 or LAU-132 launchers. Semi-active and active homing radar
and hydraulically operated fins direct and stabilize the missile on course
to the target. Propulsion is provided by a solid propellant rocket motor,
and lethality by a high explosive warhead. Performance modifications to
the AIM-54A were incorporated during and after production. The Reject Image
Device (RID), High Altitude Performance (HAP), and Extended Active Gate
(EAG) were incorporated during production. The MK 11 MOD 3 Electronics
Assembly (EA) modification was installed by retrofit after production.
The AIM-54C and AIM-54C ECCM/Sealed Missile have a Built In Self Test (BIST)
feature. BIST may be selected in conjunction with Missile On Aircraft Test
(MOAT). The AIM-54C ECCM/Sealed Missile provides two major improvements
over the AIM-54C. ECCM provides enhanced electronic protection and sealing
the missile eliminates the requirement for aircraft supplied liquid thermal
conditioning fluid during captive flight.
Guidance Section The AIM-54A RID modification offers improved capabilities
against low altitude targets over water. The EAG modification improves
capabilities against certain Electronic Counter Measure (ECM) threats.
The AIM-54C Guidance Section has a new Solid-State Receiver-Transmitter
Unit (SSRTU), Digital Electronics Unit (DEU), and Inertial Sensor Assembly
(ISA) as well as a modified guidance section wiring harness. Design improvements
reduce inherent oscillator drift, provide range discrimination, and improve
reliability. In the AIM-54 ECCM/Sealed Missile the DEU front receiver has
been modified and an improved version of the program memory has been added
to enhance ECCM capabilities. Heaters have been added, operating temperatures
of selected subassemblies have been extended, and circuit temperature compensation
has been added for sealed operation. The SSRTU has been modified to improve
ECCM performance, selected subassemblies have been improved to increase
operating temperature ranges, circuit temperature compensation has been
added for sealed operation, and the ISA has been modified to include a
heater for sealed operation.
Armament Section The AIM-54A's MK 11 MOD 3 EA modification upgrades
the Targeting Detecting Device (TDD) to improve warhead lethality against
short targets. The AIM-54C has a new TDD, the DSU-28, utilizing the MK
82 MOD 0 warhead. The MK 82 MOD 0 warhead is used with the DSU-28 on AIM-54C
All-Up-Round (AUR), serial number 83001 through 83054. A new warhead, WDU-29/B
was incorporated in the FY83 production of the AIM-54C AUR starting with
serial number 83055. The new warhead offers a 20-25 percent increase in
effectiveness. The AIM-54C ECCM/Sealed Missile uses the same armament section
as the AIM-54C.
Propulsion Section. The AIM-54A, AIM-54C, and AIM-54C ECCM/Sealed
Missile use the MK 47 MOD 1 rocket motor assembly.
Control Section The AIM-54A's HAP modification improves capabilities
against very high and fast targets. The AIM-54C Electronic Servo Control
Amplifier (ESCA) replaces the autopilot unit in the AIM-54A control section.
In the AIM-54 ECCM/Sealed Missile the Electrical Conversion Unit (ECU)
has been completely redesigned for sealed operations. The new design requires
no heater for temperature regulation.
The AIM-54 Phoenix Missile maintenance concept is based on an overall
objective to assure All-Up-Rounds are available to fulfill commitments
of operational activities and provide the means to restore unserviceable
missiles to serviceable condition with minimal downtime. Maintenance requirements
are allocated to the organizational, intermediate, and depot levels of
maintenance.
