In June Sri Lanka received its second Bay-class patrol boat from Australia. The ex- Hervey Bay , pictured here, has been renamed the Omaya and is the second unit of the class transferred to Sri Lanka. In April its navy received the sister ship ex- Corio Bay from Australia and christened her the Oshadi . Both boats had previously served with Australia’s Customs and Border Protection Marine Unit since first commissioning in early 2000. The 125-foot vessels displace 28 tons and have a top speed of just over 20 knots. With a beam of 24 feet and a draft of around 8 feet, the aluminum-built Bay class consists of eight units, all of which originally entered service between 1999 and 2000. They have a range of 1,000 nautical miles while traveling at 20 knots. They have a crew of eight, plus the ability to transport eight passengers. Each vessel is able to carry two 20-foot inspection boats and can tow craft of up to 150 tons displacement.
The navy of Togo has taken delivery of its third Defender-class boat from the United States. Manufactured by the shipbuilder Safe Boats of Bremerton, Washington, the Defender class first entered service with the U.S. Coast Guard in 2002, and many hundreds of the vessels now serve in navies, coast guards, and law-enforcement organizations around the world. Togo’s first two Defender-class units were delivered in 2010. Measuring 25 feet with a beam of 8.5 feet, a Defender-class boat is fitted with two gasoline outboard engines and can travel at speeds in excess of 40 knots. The boats typically carry a single machine gun and a crew of four, although up to six passengers can be carried on board. The boats have a bare aluminum superstructure with a polyethylene rigid-foam collar and a large pilothouse. The craft are sturdy enough to operate effectively in 6-foot seas and winds of up to 30 miles per hour.
In July Brazil signed a contract to upgrade its fleet of Mk-21A Super Lynx shipboard helicopters. Upgrades to the aircraft, which are known by the designation AH-11A in Brazilian service, will include replacement of the current power plant with new CTS800-4N engines as well as the introduction of new navigation displays and mission avionics. The new CTS800-4Ns are the same turboshafts that are used to power the British navy’s next-generation AW159 Lynx Wildcat helicopters; they will enable the Brazilian Super Lynx to benefit from increased payloads and range as well as improved performance in hot weather conditions and high-altitude environments. Planned electronic improvements to the helicopters include a new processor, satellite navigation system, radar warning, electronic-support measure and countermeasures system, and full night-vision capabilities, all of which are tied together in a new glass cockpit design. The Super Lynx upgrades are expected to begin in 2015; first deliveries are due back to Brazil in late 2017, and all eight are slated to be returned to service by 2019.
