The US Navy (USN) has revealed initial installations of its Improved Stalker (I-Stalker) Long Range Electro-Optic Sensor System (LREOSS) on two Nimitz-class nuclear-powered aircraft carriers (CVNs).
The first two I-Stalker installations were completed on board the Nimitz-class carriers USS

The l-Stalker programme, also known as AN/SAY-3, is a rapid deployment capability for fleet urgent operational needs (UONs) to support the security and protection of USN ships through the provision of improved shipboard situational awareness capabilities to combat fast attack craft/fast inshore attack craft. The system replaces the earlier Stalker LREOSS system, which is itself a modular, portable, form/fit replacement for the NATO SeaSparrow Missile System (NSSMS) MK 6 Low Light Level Television (LLLTV).
