HEL‐STAR F²®Identification Friend or Foe Helmet Mounted, Overt/Covert Marking Device

Protect yourself and your team with an active response IFF

HEL‐STAR F²® combines the helmet‐mounted, multi‐function overt/covert personnel marking functions of the HEL-STAR 6® with advanced Identification Friend or Foe (IFF) capabilities into a single unit.

Developed in close coordination with SOF users, HEL‐STAR F²® provides active IFF interrogation acquisition, response, and alert capabilities when interrogated by specified military targeting/illuminator lasers.

The battlefield is an ever changing platform with many moving pieces. While elements maneuver through the fight, the HEL-STAR F²® response helps ensure that others can identify you as a Friendly during high risk periods. When interrogated by specified military lasers, HEL-STAR F² interprets the signal and alerts against friendly fire.

HEL‐STAR F²® provides more than a full hemisphere of line‐of‐sight sensitivity to incoming laser interrogations and has been verified in formal ground testing in excess of 800 meters.

HEL‐STAR F²® includes the four marking functions of the HEL-STAR 6® with two separate operating modes (e.g. overt and covert).  User-defined functions are available in White, Green, Blue, Red, Amber and IR. The user can select custom combinations of color/emissions, steady or flashing operation, and various intensity levels.

HEL‐STAR F²® exceeds the FAA 3‐statue mile visibility requirement in the white/strobe mode.  It is shock and vibration resistant, dustproof and has been tested waterproof in open sea conditions to 130 fsw and successfully tested in the laboratory to 300 ft.

The ability to wirelessly re-program any or all of the four marker functions in the field is available with the optional Programming Interface Module or PIM.  

HEL‐STAR F²® shares the same footprint as HEL-STAR 6® and uses the same the HEL-STAR Attach Patch.

HEL‐STAR F²® is a supplemental device intended to identify and confirm a Friendly combatant.   It is not as a substitute for standing rules of engagement, and should not be used as the sole determinant for engagement of a combatant that is non-responsive to laser interrogation.
