The HARM Targeting Pod (HTS) is used on F-16 Block 50/52 aircraft to engage targets faster and more accurately when tasked with SEAD missions. The HTS pod is mounted to the side of F-16 aircraft in front of the intake. The HTS is able to detect, locate and identify ground-based emitters and assist in targeting GPS based weapons on those emitters.
The R7 incorporates a precision geolocation capability to target PGMs into the AN/ASQ 213 Pod. F-16 Block 50/52 are cleared to carry both an AN/ASQ-213 HTS R7 Pod and an ATP, by relocating HTS R7 pod to the aircraft's left inlet hard point. The system uses an integral GPS receiver, a digital receiver, and a new power supply and incorporate new software to enable users to pinpoint the location of hostile emitters using multi-ship techniques. The pod is compatible with the latest currently fielded M3.4+ F-16 OPF software. The same pod will enable pilots to utilize target location data and employ precision guided munitions to destroy hostile emitters once employed with the upcoming M4.2+ OPF release. HTS R7 will target HARM and other PGMs to destroy fixed and mobile enemy air defence elements. HTS R7 precision coordinates will be available to all Joint Forces via Link-16.
Raytheon received the contract for the development of R7 HTS in 2001 and delivered the first pod in September 2006. All current Air Force HTS pod inventory will be retrofitted to R7 over the next two years. HTS R7 will target HARM and other PGMs to destroy fixed and mobile enemy air defence elements. HTS R7 precision coordinates will be available to all Joint Forces via Link-16.
