209PN submarine for the Portuguese Navy was commis- sioned at Howaldtswerke-Deutsche Werſt (HDW), part of TyssenKrupp Marine Systems in Kiel, Germany. Te new submarine, named NRP Arpão, is equipped
with an air-independent fuel cell propulsion system and combines the proven design principles of the Class 209 family with the innovative features of Class 214. Te contract for the two Class 209PN submarines
was signed in 2004. A sister to NRP Arpão, NRP Tridente, was delivered in June 2010.
NRP Arpão is the second of two Class 290PN submarines for the Portuguese Navy.
Sandown and HMS Inverness – were decommissioned and sold to Estonia in 2006. Te vessels were re-named ENS Admiral Cowan and ENS Sakala. As part of a programme to return the two ships to
operational service, Tales originally signed a contract in 2006 to provide operational support to the ships in service and upgrades to Tales’s highly successful Sonar 2093 system. Tis new contract now extends the support programme until December 2011. Sonar 2093 is a variable-depth sonar system and is
designed for the detection and classification of bottom and moored mines. It is optimised for littoral (coastal) and open-ocean waters and is effective against all known mine types. Te system is in service with the RN’s remaining
Sandown-class MCMVs, and existing export contracts include Japan, Australia, Saudi Arabia, Turkey, Italy and the Republic of Korea.
Mine countermeasures US Navy acquires
MCM software Te US Military has acquired six upgraded licences for underwater situational awareness technology for supporting clearance diving and mine countermeas- ures (MCM) forces. Te soſtware known as SeeTrack Military or Common Operator Interface Navy (COIN) was specifically tailored for the US Navy and developed by Scottish-based soſtware company, SeeByte. Te newest version comes with two modules – Perfor-
mance Analysis Training Tool (PATT) and Automated Target Recognition (ATR) using Computer-Aided Detection & Computer-Aided Classification (CAD/ CAC) components. They are designed to provide a higher level of

Thales support deal Tales has signed a contract with the Estonian Navy to provide an additional 12 months of technical support and maintenance to two former Royal Navy (RN) mine countermeasures vessels (MCMVs) now serving with the Estonian fleet. Te contract was signed by the Chief of the Estonian

awareness, accuracy and confidence within the context of the individual systems’ sortie and overall MCM Mission. Te modules are visualised in the current COIN and SeeTrack Military software, originally developed by SeeByte specifically for US Navy EOD Forces, but now deployed in 10 NATO and NATO Friendly Nations’ Navies. Te ATR module uses CAD/CAC to detect specific
regions in side-scan sonar data that potentially correspond to an object previously learned by the system. Multiple CAD detectors identify and discrimi- nate objects several times providing better accuracy in mine detection. Obvious false alarms are removed by the CAC component creating an accurate map of contacts for operators to examine within the surveyed
