UH-1H Aircraft Survivability Equipment (ASE)

Generally, ASE can be defined as equipment that hinders the enemy's ability to acquire and engage your aircraft, that is, assist you against the air defense threat. While there are other things (IFF, KY-58's, etc.) that increase your combat effectiveness, these other devices do not meet the criteria of the general definition above and were not considered by FM 1-101 to be ASE. The UH-1H had only two types of ASE that may be installed, an APR-39 radar warning receiver and infrared suppression.

 

Radar Warning

The only evidence of the APR-39 on our aircraft is the 2 forward antenna mounts on the nose and the cover plate on the dash for the display unit. We will probably never see an installed APR-39 in our Hueys.

Infrared Suppression

The predominate ASE. The paint on all tactical Army aircraft is low-reflecting and helps you blend into the terrain.

Infrared Suppression

The upturned insulated exhaust duct assembly can be installed to insulate and direct hot exhaust into the rotor wash. Yes, you're allowed to call it a "toilet bowl."

 

 

Infrared Suppression

An oil cooler exit shield can be installed below the oil radiators. It merely shields this hot area of the aircraft from direct view of thermal sights and IR seeker heads.

 

Infrared Suppression

2 engine side shields can be installed to shield the hot engine. Without these, there is nothing more than a wire mesh between your hot engine and the bad guys.
