IMPROVED LPRF (iLPRF)
The LPRF is a critical component to the APG-66(V) and (V)2 Fire Control RADAR in the F-16, as well as many other airborne platforms. Due to the age of the LPRF, it is plagued by a low mean time between failure (MTBF) as well as diminishing manufacturing sources and materials shortages (DMSMS). The Improved LPRF (iLPRF) was designed as a form, fit, function replacement to combat these issues. Utilizing the existing qualified chassis, the iLPRF design replaces the obsolete and hard-to-find subassemblies with modern, supportable, and high MTBF components. The iLPRF provides very quick return on investment, and keeps operational availability of the line replaceable unit (LRU) high.

- Form-Fit-Function retrofit for APG-66 LPRF
- Mitigates obsolescence by removal of problematic RF SRU’s, but retains some original components to reduce costs and requalification efforts
- High Mean Time Between Failure
- Long-Term Sustainable Design
- Quick Return on Investment
- No Minimum Quantity Requirements for Upgrade
- All work performed at Duotech’s facilities and tested in accordance with OEM & USAF standards
- Reduce repair turnaround time with off-the-shelf components
- LRU can be reprogrammed to different channels to match Northrop’s original G0X configurations
- Take old non-repairable LRUs from stock to create new rotatable stock
- Upgrade non-usable Baseline LPRFs to (V)2 compatible LRPFs
