The Phoenix (IR-15) NSN 5855-01-396-8734 is a programmable Infrared Beacon which is powered by one nine volt battery. The Phoenix  delivers a powerful infrared flash which can only be seen with night vision equipment such as the AN/PVS-7 B/D, AN/PVS-14 and AN/AVS-9 at distances of over five miles and can also be seen through clothing and underwater.

The Phoenix  has a six second memory which can be programmed to flash in any sequence which the end user inputs (such as a Morse type code). This is accomplished by shorting two pins located on top of the Phoenix. Removal of the battery deletes any stored codes and miniature indicator lights allow the end user to visually verify the correct input of his assigned code or flash sequence.

The Phoenix  has proven itself useful in both Combat and Covert operations, some of which include: identifying personnel and friendly forces, marking vehicles and convoys, outlining safe pathways, trails or installations.
