The Gulfstream G550 Nachshon Oron is an Israeli special-mission aircraft that adapts a U.S.-built Gulfstream G550 business jet with IAI/ELTA radar, electro-optical, SIGINT, C4I, and AI-assisted processing systems. Operated by Israeli Air Force 122 Squadron, it is documented in wartime intelligence, surveillance, early-warning, and targeting-support roles over Gaza and during Israel's 2025 operations against Iran.

Specifications

Airframe
Gulfstream G550 business jet modified as an Israeli special-mission aircraft
Mission suite
IAI/ELTA AESA radar, electro-optical sensors, SIGINT equipment, C4I systems, and AI-assisted data processing
Operator
Israeli Air Force 122 Squadron (Nachshon)
Crew / mission personnel
Reported accommodation for eight intelligence officers, in addition to flight crew
Operating altitude
Reported operations above 40,000 ft; IAI says the aircraft can climb to 40,000 ft in about 25 minutes
Endurance
About 5-10 hours per mission in Israeli reporting; IAI describes roughly 10 hours airborne

Mission Architecture

Oron combines a long-range business-jet platform with Israeli mission systems rather than acting as a strike aircraft itself. Public sources describe radar, electro-optical, SIGINT, C4I, and onboard data-processing equipment used to build a real-time intelligence picture for commanders and strike forces.

Public sources sometimes group the Nachshon fleet under G550 wording, but Shavit-specific imagery and specialist references identify the aircraft as the earlier Gulfstream V/G500 SIGINT member alongside the G550 Eitam and Oron aircraft.

It is built for long-range, high-altitude intelligence, surveillance, target acquisition, reconnaissance, and multi-payload missions, with official specifications listing a 5,670 kg maximum takeoff weight, more than 30 hours endurance, beyond-line-of-sight SATCOM operation, and payload capacity far above the smaller Heron 1. Conflict sourcing ties the type to Israeli Iron Swords surveillance sorties and Operation Rising Lion missions over Iran.

IAI describes Heron 1, known in Israeli service as Shoval, and Heron Mk II as SATCOM-capable MALE platforms with automatic taxi, takeoff, and landing, while conflict sourcing ties the family to Israeli operations in Gaza and Iran, Azerbaijani reconnaissance and targeting in Nagorno-Karabakh, and Indian Heron Mk II operations during Operation Sindoor.
