Sweden's Saab has begun marketing its IR-OTIS infra-red search and track (IRST) system for South-East Asian fighter upgrades. Saab says the system is well-suited for Northrop F-5 upgrade programmes and, possibly, for Lockheed Martin F-16s. Singapore has recently upgraded its F-5 fleet, while Indonesia and possibly Malaysia are set to follow. Thai upgrade plans for F-16s have been shelved.
