Plans are being developed by the US Naval Air Systems Command (NAVAIR) for the upgrade of seven Royal Thai Navy (RTN) Dornier 228 maritime surveillance aircraft under the US government-funded Building Partner Capacity programme.
Used for maritime patrol and exclusive economic zone surveillance, the Do 228 aircraft are currently configured with a Telephonics RDR 1550B radar and a FLIR Systems Star SAFIRE II electro-optical/infrared (EO/IR) turret. According to a request for information (RFI) issued by NAVAIR on 23 April, the planned upgrade will include the introduction of new sensors and mission systems.
Specific components listed in the RFI include a multimode radar with a minimum detection range of 160 n mile (296 km); an EO/IR five-axis stabilised multipayload system; a communications package including beyond line of sight (X-band) and datalink; avionics systems including navigation, automatic direction finding, instrument landing system, flight management system, traffic alert and collision avoidance system, and ADS-B transponder; a mission operator station and operating software; AIS; electronic support measures; and a mission data recorder.
