The S1850M is a long range passive electronically scanned array radar for wide area search. The S1850M is produced by BAE Systems Integrated System Technologies (formerly AMS UK) and Thales. It is a modified version of the Thales Nederland SMART-L radar. The S1850M is advertised as being capable of fully automatic detection, track initiation and tracking of up to 1,000 targets at a range of . It is also claimed to be highly capable of detecting stealth targets, and is able to detect and track outer atmosphere objects at short range, making it capable of forming part of a Theatre Ballistic Missile Defence system. The contract for initial production of the S1850M was signed in 2001; 2 for the UK, 1 for France and 1 for Italy, with a common prototype based in Toulon. In 2005 a follow-on contract was signed for 5 more for the UK, 1 more for France and 1 more for Italy. Even a stronger version of the S1850M is under testing, which is actually an updated version of the current SMART-L radar, which the Dutch Navy will call the SMART-L-EWC (Early Warning Capability) Radar, with even a greater search radius and capable of detecting ballistic missiles. It would have a tracking range of 2000km for ballistic missile defence and 480km for air defence . SMART-L EWC is an AESA programmable radar which is characterized by full flexibility. Additional capabilities can be introduced during lifetime according to customer needs. This makes the radar future proof in case of evolving requirements. 〔(), Thales SMART-L-EWC.〕 ==Applications== * UK Royal Navy: Type 45 destroyer and (future) Queen Elizabeth-class aircraft carrier * France: Horizon class frigate * Italy: Orizzonte class frigate In all its current applications the S1850M is the long range radar (LRR) component of the Principal Anti Air Missile System. On the Type 45 destroyers it is paired with the SAMPSON multifunction radar, on the Horizon ships it is paired with the EMPAR multifunction radar. On 11 February 2009, Thales indicated that the S1850M radar will be fitted on the Royal Navy's ''Queen Elizabeth'' class aircraft carrier. 〔(【引用サイトリンク】title=United Kingdom selects Thales's S1850M radar for new aircraft carriers )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「S1850M」の詳細全文を読む スポンサード リンク
