L3Harris Technologies is a public U.S. defense and aerospace company headquartered in Melbourne, Florida. The company says it was formed when L3 Technologies and Harris Corporation completed their merger in June 2019, and its public materials emphasize technologies across air, land, sea, space, and cyber domains.

For this catalog, the builder page groups cataloged systems tied to L3Harris' electronic warfare, communications, airborne missionization, and counter-UAS work. That context is most visible in the EA-37B Compass Call and VAMPIRE entries, which show how the company appears in the modern defense-industrial side of the catalog.

The system is vehicle and platform agnostic, combines a WESCAM MX-10D RSTA sensor with APKWS or other laser-guided munitions, and has been used in Ukraine to defend against hostile unmanned systems and selected ground threats. L3Harris later expanded VAMPIRE into land, maritime, airborne, base-defense, and electronic-warfare variants, with U.S. Army orders adding a proximity-fuze APKWS configuration.

It combines two BRU-46/A pyrotechnic ejector units with smart-rack electronics, was certified on Block 40/42/50/52 F-16 aircraft with WCMD weapons in 2004, and supports JDAM and JSOW carriage. DVIDS imagery documents the rack on a U.S. F-16 at Bagram Air Field during Operation Freedom's Sentinel support in Afghanistan.
