This night there were an usual Israeli activity over central Mediterranean Sea: at least two Gulfstream 550 Nachshon Aitam (537 & 569) one Gulfstream G-V Nachshon Shavit (679), one Lockheed C-130J and one Boeing 737 (IAI telemetry) left Israel westbound.
At least one of Gulfstream 550 Nachshon Aitam arrived just off Tunisia (around 03:15 CEST).
Another one (679) switched off its ADS-B trasnsponder over Crete
The reason of this activity is the launch of a new advanced Israeli spy satellite Ofek16.
In a statement on Monday, Israel’s Ministry of Defence and Israel Aerospace Industries said “Ofek 16” was shot into space at 4am local time [03:00 CEST].
The “electro-optical reconnaissance satellite with advanced capabilities … will undergo a series of tests,” it added.
