Weapons & equipment Saab secures lightweight
torpedo deal Defence and security company Saab has received an order from the Swedish Defence Materiel Administra- tion (FMV) regarding design plans for a new lightweight torpedo (NLT). Te order is part of a letter of intent regarding the
Swedish armed forces’ underwater capability which was announced on 9 June 2014. “We are very pleased to commence work to deliver a
replacement for the Torpedo 45,” said Görgen Johans- son, senior vice president and head of business area at Saab Dynamics.
Support/maintenance
Adelaide-class frigate maintenance contract signed
Australia’s Minister for Defence David Johnston has announced that Tales Australia Ltd has been awarded the Royal Australian Navy’s Adelaide-class guided missile frigate group maintenance contract. Senator Johnston said the contract will be for an initial period of four-and-half years with the potential for contract extensions to an anticipated value of A$130 million (US$121.8 million).
“If contracted quality and service level requirements
are met and efficiencies are achieved, the contract can be extended to the ship’s withdrawal from service dates,” Senator Johnston said. Senator Johnston said this was the second of
the grouped-asset, long-term, performance-based contracts for the repair and maintenance of the Royal Australian Navy’s major surface ships. Work on the frigates will be undertaken at Navy’s
Garden Island facility in Sydney. Propulsion

embraces hybrid drive GE’s Power Conversion business has confirmed that it is working with Daewoo Shipbuilding and Marine Engineering (DSME) in South Korea to provide an electrical power and propulsion system for the Norwegian Defence Logistics Organisation’s (NDLO’s) logistics and support vessel (LSV). GE’s equipment will be installed as part of the ship’s hybrid propulsion system, improving fuel efficiency and operating flexibility. In October 2012, GE’s Power Conversion business
announced a similar project for the UK Royal Fleet Auxiliary’s new fleet of four military afloat reach and sustainability (MARS) tankers. Tese will be the UK’s next-generation class of large, fast-fleet tankers that will deliver fuel, fresh water and supplies to Royal Navy ships including the Queen Elizabeth-class aircraſt carriers. Once completed, the LSV, which is being built by
DSME, will be 180m in length with a beam of 26m and will have a loaded displacement of more than 26,000tonnes. The new vessel is planned to enter service in October 2016. Hybrid propulsion systems like the one being used
for this project combine electrical and mechanical equipment to turn the ship’s propellers through- out the speed range. Te Norwegian LSV will have two independent propeller shaſts, each driven via a gearbox by either a large propulsion diesel or a relatively small electric motor. When the ship is operating at moderate or low

speeds, the propeller shaſts are turned using GE’s electric motors, with speed control for each motor provided by the use of a low-voltage variable speed drive. Te electri- cal power for the motors is supplied from the generators used to supply the remainder of the ship’s services. Tis reduces the number of generators in operation and oſten allows those that are in use to be run at a more efficient operating point. When the ship is required to operate at higher speeds, the main propulsion diesel engines are started
