IR PAINT
LIN: J01849
GENERAL:
The AN/ALQ-144A(V)1 CMS is the upgrade version of the AN/ALQ-144(V)1. It is an active, continuously operating, omni-directional and electrically fired infrared (IR) jammer. This CMS is designed for use on helicopters to confuse or decoy threat IR missile systems.
PHYSICAL CHARACTERISTICS:
The AN/ALQ-144A(V)1 CMS consists of a transmitter assembly and an operator control unit. The operator control unit has a nine pin connector assembly. The total system weight is 30 pounds.
THREAT COVERAGE:
The AN/ALQ-144A(V)1 CMS is designed to provide jamming of all known IR threat missile systems when operated on helicopters equipped with low reflective paint and engine exhaust suppressors.
AIRCRAFT APPLICABILITY:
OH-58D, EH-60A, UH-60A/L, MH-60K
SPECIAL TEST EQUIPMENT:
| AN/ALM-178 | Test Set (AVIM) |
LIN: J01917
GENERAL:
The AN/ALQ-144A(V)3 CMS is the upgrade version of the AN/ALQ-144(V)3. It is an active, continuously operating, omni-directional and electrically fired infrared (IR) jammer. This CMS is designed for use on helicopters to confuse or decoy threat IR missile systems.
PHYSICAL CHARACTERISTICS:
The AN/ALQ-144A(V)3 CMS consists of a transmitter assembly and an operator control unit (OCU) with dual capabilities. The OCU controls both the AN/ALQ-136(V)1/5 and the AN/ALQ-144(V)3 or AN/ALQ-144A(V)3. The OCU has a 25 pin connector assembly. The total system weight is 30 pounds.
THREAT COVERAGE:
The AN/ALQ-144A(V)3 CMS is designed to provide jamming of all known IR threat missile systems when operated on helicopters equipped with low reflective paint and engine exhaust suppressors.
AIRCRAFT APPLICABILITY:
AH-1F, AH-64A/D
SPECIAL TEST EQUIPMENT:
| AN/ALM-178 | Test Set (AVIM) |
IR paint was developed to provide reduced IR and optical signatures for tactical aircraft. Aviation Electronic Combat equipment requirements are compatible with either the lacquer acrylic or polyurethane base paints. The polyurethane based IR paint, applied to all fixed wing Special Electronic Mission Aircraft, comes in numerous colors. It provides enhanced Nuclear, Biological and Chemical protection as well as low IR and optical signatures and improved maintenance characteristics.
PHYSICAL CHARACTERISTICS:
Lacquer Acrylic Paint (MIL-L-46159A). This IR paint is aircraft green in color and provides a nonspecular, low IR reflective surface for the rotary wing aircraft.
Aliphatic Polyurethane Paint (MIL-C-46168A). This IR paint has chemical resistant qualities and aircraft painted with it can be readily decontaminated. Under the Chemical Agent Resistant Coating Program, the Army has mandated that this paint be applied to all tactical aircraft. The paint is superior in durability and provides low reflective properties for reducing IR and optical signatures. It is available in quart, gallon, 5-gallon and 55-gallon containers. There are 12 different colors for insignia, interior and exterior painting.
THREAT COVERAGE:
The paint provides increased protection against IR and optical threats by reducing the aircraft's IR and optical signatures.
AIRCRAFT APPLICABILITY:
All tactical Army aircraft
