Melbourne-based BMT Design & Technology (BMT),a subsidiary of BMT Group Ltd, has completed a study for the Commonwealth of Australia, to examine a range of options for the Life of Type Extension (LOTE) of a wide range of Defence Maritime Platforms. This included the entire surface fleet of the Royal Australian Navy (RAN), through to the LCM (Landing Craft Mechanised) and LARC (Lighter Amphibious Resupply Cargo) vehicles of Army Marine.
Undertaking the study in two stages over the course of 12 months, BMT developed a risk-based approach to assess the viability of LOTE for 11 classes of ship. Unlike the approach taken by others, BMT recognised the importance of ensuring the study was not limited solely to material/condition surveys and incorporated the Fundamental Inputs to Capability (FIC). This allowed the full costof operating the fleet within the various LOTE scenarios to be identified.
As well as identifying the costing options, the study provided an understanding of any impact on achieving availability targets while satisfying safety, environmental and technical risk imperatives.
Peter Sanders, Principal Consultant at BMT Design & Technology comments: “Our intimate understanding of the defence engineering environment provided the customer with the confidence that we could deliver a comprehensive study which met their requirements. We were also able to draw upon the knowledge and expertise from our sister companies, BMT Isis and BMT Defence Services, both of which have extensive experience of working in the defence sector.”

Northrop Grumman Corporation has taken another significant step to reduce the risks and costs associated with producing an extremely high frequency (EHF) satellite communications system for the U.S. Air Force’s B-2 stealth bomber. Company Proves New Antenna Can Communicate, Operate With On-Orbit Satellite
In a demonstration conducted Northrop Grumman proved that a new active electronically scanned array (AESA) antenna it has developed for the B-2 can establish and maintain communications services with an on-orbit Air Force Advanced EHF (AEHF) communications satellite. The demo included the antenna, a Navy Multi-band Terminal and the satellite.
Northrop Grumman is the Air Force’s prime contractor for the B-2, the flagship of the nation’s long range strike arsenal, and one of the world’s most survivable aircraft. An EHF satellite communications system would allow the B-2 to send and receive battlefield information significantly faster than its current satellite communications system.
“Our demo marks the first time that AESA antenna technology has been used to communicate with the AEHF network,” said Byron Chong, Northrop Grumman’s B-2 deputy program manager. “We showed that our antenna will consistently produce and maintain the high-gain beam needed to communicate with AEHF satellites.”
During the test, he added, Northrop Grumman successfully demonstrated extended data rate (XDR) communications between the AESA antenna and the AEHF satellite at EHF frequencies. XDR communications take advantage of the AEHF satellites’ most advanced, most secure signaling protocols and communication waveforms.

Boeing on Nov. 2 delivered the fifth production P-8A Poseidon aircraft to the U.S. Navy. The P-8A is one of 24 low-rate initial production (LRIP) maritime patrol aircraft that Boeing is building for the Navy as part of contracts awarded in 2011 and 2012.
“This is our final P-8A delivery of the year; we’ll ramp up to 12 deliveries, including P-8I aircraft for India, in 2013,” said Chuck Dabundo, Boeing vice president and P-8 program manager. “Our in-line production approach, which draws on processes developed on the company’s commercial and military programs, has been key to our ability to increase production rates while reducing costs.”
“As we transition to the P-8A and prepare for Initial Operational Capability in 2013, the U.S. Navy is successfully flying the first production planes at Naval Air Station Jacksonville, Fla.,” said Capt. Aaron Rondeau, U.S. Navy P-8A Integrated Product Team lead.
The next three Poseidon aircraft are undergoing mission systems installation and checkout in Seattle, and two more are in final assembly in Renton, Wash. Boeing will deliver its sixth production P-8A to the Navy in early 2013.
The Navy plans to purchase 117 of the Boeing 737-based P-8A anti-submarine warfare, anti-surface warfare, intelligence, surveillance and reconnaissance aircraft to replace its P-3 fleet.
As part of the LRIP contracts, Boeing is also providing aircrew and maintenance training for the Navy, in addition to logistics support, spares, support equipment and tools.

The U.S. Navy supported the Oct. 23 launch of a U.K. Royal Navy Trident II D5 Fleet Ballistic Missile (FBM) built by Lockheed Martin. The unarmed missile was launched from the submerged Royal Navy submarine HMS Vigilant in the Atlantic Ocean.
The test marked the 143rd successful test flight of the Trident II D5 missile since design completion in 1989 – a reliability record unmatched by any other large ballistic missile or space launch vehicle.
“The Royal Navy and the U.S. Navy continue to demonstrate the readiness and reliability of this highly capable system,whose mission is to discourage aggression,” said Melanie A. Sloane, vice president of Fleet Ballistic Missile programs, Lockheed Martin Space Systems Company, the Trident missile prime contractor. “The cooperation of both governments, supported by industry, provides a credible submarine-based strategic deterrent.”
The test, which was part of a Demonstration and Shakedown Operation that verified the integrity of the strategic weapon system following an overhaul of the submarine, was the 10th consecutive successful Trident II D5 missile test flight by the U.K. since 1994. The missile was converted into a test configuration using a test missile kit produced by Lockheed Martin that contains range safety devices, tracking systems and flight telemetry instrumentation.
First deployed in 1990, the D5 missile is currently aboard U.S. Navy OHIO-class and Royal Navy VANGUARD-class submarines. The three-stage, solid-propellant, inertial-guided ballistic missile can travel a nominal range of 4,000 nautical miles and carries multiple independently targeted reentry vehicles.
