Myanmar Navy commissions first corvette with reduced RCS

29 December 2016

The Myanmar Navy (MN) commissioned several new vessels on 24 December, including UMS (Union of Myanmar Ship) Tabinshwehti with pennant number 773: the service’s first guided-missile corvette featuring radar cross-section (RCS) reducing characteristics.

Launched in late November 2014, UMS Tabinshwehti is also the third guided-missile corvette to enter service with the MN. Unlike the two older 77 m guided missile corvettes, UMS Anawrahta (771) and UMS Bayintnaung (772), the recently commissioned corvette has a reduced-RCS superstructure with two masts and a helicopter hangar.

Weapons include one Oto Melara 76 mm gun in a stealthy cupola and two Chinese-made NG-18 gun systems for close-in defence. The ship also features a box launcher for six man-portable air defence systems (MANPADS) – presumably from North Korea.

Moreover, two sets of five-barrelled Chinese-origin RDC anti-submarine rocket launchers are mounted ahead of the main gun and what appear to be two sets of two box launchers for Chinese C-802-series anti-ship missiles are fitted amidships.

The commissioning ceremony, which took place on the MN’s 69th anniversary, was attended by the commander-in-chief of the country’s armed forces, Senior General Min Aung Hlaing, who noted that Myanmar is now capable of constructing missile corvettes to its own specifications from start to finish. “Building warships on a self-reliant basis saves money and provides benefits to Myanmar,” he added.

The MN also displayed a locally developed unmanned surface vessel (USV) project using what appears to be a rigid-hull inflatable boat (RHIB) from French manufacturer Sillinger fitted with what appears to be a remotely operated machine gun.

Video footage of the demonstration suggests that the USV is controlled by two operators using a commercial-off-the-shelf-based control system with joystick controls and a line of sight radio control.

Other vessels commissioned on 24 December include a 77 m troop transport ship UMS Chindwin and six 29 m landing craft mechanised (LCM) vessels capable of carrying two armoured fighting vehicles.

US Air Force to asses improved Scorpion jet

Revamped Scorpion jet to begin Air Force assessment

By Jerry Siebenmark | The Wichita Eagle (Tribune News Service) | Published: December 27, 2016

With the successful first flight of Textron’s first production-conforming Scorpion jet, the aircraft enters a first-of-its-kind evaluation program with the Air Force.

Last week, the latest version of the Scorpion tactical jet — featuring improvements suggested by potential customers based on the prototype Scorpion that first flew three years ago this month — took off from McConnell Air Force Base for a one-hour, 42-minute flight.

Changes to the production-conforming Scorpion included 4 degrees of sweep to the wings, an enhanced aft horizontal stabilizer and a simplified landing gear design.

Officials from Textron AirLand, a unit of Textron Inc., said during the test flight that they verified the Scorpion’s newly configured Garmin G3000 avionics and aerodynamic performance as well as a number of other aircraft systems.

Now, the revamped twin-engine, multimission jet will undergo an assessment by the Air Force Airworthiness Office.

That assessment will be performed by way of the Cooperative Research and Development Agreement reached in August between the Air Force and Textron Air Land. Air Force officials said the assessment is unique because it has never done a CRADA involving an airplane that it doesn’t formally plan to buy.

“We have not done a CRADA like this before and we have never had a partnership with industry to assess aircraft that are not under a USAF acquisition contract,” Jorge Gonzalez of the Air Force Technical Airworthiness Authority said in a news release announcing the agreement.

Gonzalez also will oversee the Scorpion assessment program.

The Air Force said the assessment is important to making direct, commercial sales of the airplane to foreign military services.

Since the first flight of the prototype Scorpion in December 2013, it has accumulated more than 800 flight hours and flown to 10 countries for demonstrations to foreign military services. The jet was designed and built in Wichita. Textron AirLand says the subsonic Scorpion can be used for intelligence gathering, surveillance and reconnaissance, and close air support missions.

MK 48 Mod 7 Common Broadband Advanced Sonar System (CBASS) Heavyweight Torpedo

Lockheed Martin designed and developed the MK 48 Mod 7 Common Broadband Advanced Sonar System (CBASS) submarine-launched heavyweight torpedo for the US Navy.

The torpedo, which has advanced counter-countermeasure capabilities, is operational with the US and its allied submarine fleet, and serves as a highly effective and lethal weapon against anti-surface and anti-submarine threats in deep and shallow waters.

The heavyweight torpedo is equipped with advanced commercial-off-the-shelf technologies to provide superior reliability and performance against challenging threats in both littoral and blue water environments, and can support multi-band operation.

MK 48 Mod 7 CBASS development details

The MK 48 Mod 7 CBASS is an upgraded version of the MK 48 Advanced Capability (ADCAP) Mod 6 Advanced Common Torpedo (ACOT), manufactured by Raytheon. The new torpedo was developed as part of an Armaments Cooperative Programme between the US Navy and the Royal Australian Navy.

MK 48 Advanced Capability (ADCAP) Mod 6


The Mk-48 has been operational in the US Navy since 1972. MK-48 ADCAP (Advanced Capability) became operational in 1988 and was approved for full production in 1989. The USS NORFOLK (SSN 714) fired the first ADCAP torpedo on July 23, 1988, sinking the FORREST SHERMAN-class destroyer JONAS INGRAM (DD 938).

Mk-48 and Mk-48 ADCAP torpedoes can operate with or without wire guidance and use active and/or passive homing. When launched they execute programmed target search, acquisition and attack procedures. Both can conduct multiple reattacks if they miss the target.


A highly capable weapon, the Mk-48 can be used against surface ships or submarines, and has been test fired under the Arctic ice pack and in other arduous conditions. The ADCAP version, in comparison with earlier Mk-48 torpedoes, has improved target acquisition range, reduced vulnerability to enemy countermeasures, reduced shipboard constraints such as warmup and reactivation time, and enhanced effectiveness against surface ships. The Mk-48 is propelled by a piston engine with twin, contra-rotating propellers in a pump jet or shrouded configuration.


The engine uses a liquid monopropellant fuel, and the torpedo has a conventional, high-explosive warhead. The Mk-48 has a sophisticated guidance system permitting a variety of attack options. As the torpedo leaves the submarine’s launch tube a thin wire spins out, electronically linking the submarine and torpedo. This enables an operator in the submarine, with access to the submarine’s sensitive sonar systems, initially to guide the torpedo toward the target. This helps the torpedo avoid decoys and jamming devices that might be deployed by the target. The wire is severed and the torpedo’s high-powered active/passive sonar guides the torpedo during the final attack.

cbass-mark-48-22-aug-2014MK 48 Mod 7 CBASS

The US Navy awarded a five-year fleet-wide CBASS programme to Lockheed Martin in 2011 to modernise a total of 1,263 MK 48 torpedoes deployed by the entire submarine fleet as anti-submarine or anti-surface warfare weapons. The company received a contract worth over $50.68m for functional item replacement kits, engineering services, spare parts and production support material in March 2011.

The upgrade kit consists of a broadband analogue sonar receiver, a guidance and control box, a pre-amplifier, guidance and control materials, and cable assemblies. It provides increased bandwidth and streamlined targeting and tracking capabilities to the heavyweight torpedo.

Lockheed Martin secured a $37m contract from the US Navy in August 2013 to provide Mod 7 CBASS replacement kits and services for the MK 48 heavyweight torpedoes in service with the US Navy and allied naval customers from Canada and the Netherlands. Polaris Contract Manufacturing, a subsidiary of Lockheed Martin, is responsible for building the circuit card and module assembly. Completion of the work is scheduled for July 2017.

Lockheed Martin was awarded a $10m contract by the Naval Sea Systems Command (NAVSEA) in April 2014 to provide maintenance support for all MK 48 torpedoes.

Design and features of the MK 48 Mod 7 CBASS

The MK 48 Mod 7 CBASS torpedo has a length of 5.8m and diameter of 53cm, and can reach a maximum depth of 1,200ft. It weighs 1,676kg and carries a high explosive warhead of 292.5kg.

Active and passive homing guidance is provided by the Common Broadband Advanced Sonar System. The torpedo can effectively engage low-Doppler shallow submarines, fast deep diving submarines and high-performance surface ships.

It supports autonomous fire-and-forget operation or wire-guide capability to provide post-launch monitoring and updates through the submarine combat system. It also allows the transmission and reception over a wide frequency band. The broadband signal processing techniques ensure improved search, acquisition and attack effectiveness for the torpedo.

The Navy Just Got A SUPER Explosive New Toy: Here


According to Scout Warrior, the new MK 48 will be the first upgrade to U.S. torpedoes since the MK 48 Mod 7 was put into service in 2006. The new variant will have an improved acoustic receiver, new guidance-and-control hardware, and improved memory and processing power for better performance against evolving threats.

The new MK 48 heavyweight torpedo is just one of the 20 upgrades Lockheed Martin supplies to the Navy every month, according to senior Lockheed official, Tom Jarvo.

“A heavyweight torpedo is unmatched in its ability to sink things,” Richard said about the 650-pound high-explosive warhead. “The Mk 48 is a unique capability in the fleet.”

Mk 48 Mod 7 CBASS submarine torpedoes

The CBASS broadband sonar makes the torpedo more effective against emerging submarine classes in the harshest of acoustic environments, Lockheed Martin officials say. The Mark 48 Mod 7 CBASS torpedo uses modern commercial-off-the-shelf (COTS) technologies in an open-architecture computing environment, and can be improved with regular hardware and software upgrades.

MK 48 Guidance and Control Section


Lockheed Martin provides the U.S. Navy the latest advancements in sonar systems for guidance and control systems for the MK 48 Mod 7 torpedo. The Lockheed Martin guidance and control systems will equip the heavyweight torpedoes with increased bandwidth and streamlined targeting and tracking capabilities. These systems will optimize the MK 48’s effectiveness as well as provide advanced counter-measure capabilities.

Lockheed Martin provides fully integrated guidance and control sections to increase the inventory of MK 48 torpedoes over several years. The expectation is that the production orders will range with the potential for more than 250 torpedoes over the next five years for the U.S. Navy, which are used by all classes of submarines as their anti-submarine warfare (ASW) and anti-surface warfare (ASuW) weapon.

The guidance and control systems for MK 48 torpedoes include the same section of the Navy’s existing heavyweight torpedoes that Lockheed Martin is upgrading under the MK 48 Common Broadband Advanced Sonar System (CBASS) awarded by the U.S. Navy in 2011. Lockheed Martin delivers to the U.S. Navy at least 20 Mod 7 CBASS kits per month and is on track to deliver all kits on schedule. Lockheed Martin also performs work intermediate maintenance of these torpedoes for fleet training, giving the Navy a critical combat advantage.

Surprise move Canada block military equipment sales to Thailand but earlier approved sales to Saudi Arabia

Canada blocks sale of defence equipment to Thailand

21 December 2016

Canada’s Minister of Foreign Affairs Stéphane Dion has recently blocked the sale of military equipment to Thailand, the Canadian government has confirmed to IHS Jane’s.

A spokesperson for Global Affairs Canada (GAC) – the government department that oversees the country’s foreign relations and trade – did not provide details about the type of equipment that was barred from sale but said the value was “modest”.

The spokesperson indicated that the sales ban was decided on a case-by-case basis and that it was a response to Canada’s concerns about Thailand’s human rights record. The Southeast Asian country has been governed by the military since a coup d’etat in May 2014.
