Finmeccanica company Selex ES has been contracted to supply a new electronic warfare (EW)/ defensive aids system (DAS) suite for eight Brazilian Navy Lynx Mk 21A helicopters being upgraded by sister Finmeccanica business AgustaWestland.
The updated platform self-protection fit will comprise the new SAGE electronic support measures (ESM) system and a DAS controller − both supplied by Selex ES − plus a third-party countermeasures dispensing system.
AgustaWestland was last year awarded a contract worth more than USD160 million for the mid-life upgrade of eight Lynx Mk 21A helicopters serving with the Força Aeronaval da Marinha do Brasil. The modernisation also includes replacement of the original Rolls-Royce Gem engines with the more powerful LHTEC CTS800-4N, a new ‘glass’ cockpit, and a new electrically powered rescue hoist.
Working under contract to AgustaWestland, Selex ES will supply its SAGE digital ESM system. SAGE will provide a wideband radar warning capability (primarily aimed at platform protection) and a narrowband fine angle of arrival and geo-location capability (to be used primarily for surveillance/ intelligence collection). The associated DAS controller will cue a countermeasures dispenser system.
According to Selex ES, the SAGE system for the Lynx Mk 21A upgrade will be supplied with a suite of EW operational support tools for mission data programming and replay. This will provide the Brazilian Navy with the ability to independently and responsively update the system library to recognise emergent radar threats.
Variants of SAGE have previously been selected for the Republic of Korea Navy’s Maritime Operational Helicopter programme, and for the Indonesian Air Force’s CN-235 maritime patrol aircraft upgrade. The SAGE ESM system has also been supplied to the UK Ministry of Defence for an undisclosed application.
