Key Points

  • Thailand will equip its offshore patrol vessels with the H145M helicopter
  • Aircraft will bolster the patrol vessels’ maritime surveillance and search-and-rescue capabilities

The Royal Thai Navy (RTN) is planning to deploy its new H145M light utility twin-engine helicopters from its Pattani- and modified River-class offshore patrol vessels (OPVs), the service’s 202 Squadron confirmed with IHS Jane’s on 5 May.

The RTN completed technical acceptance of its first two H145M aircraft from Airbus Helicopters on 29 April. The aircraft are part of a 2014 contract for five airframes. However, the first two helicopters will remain in Germany for a pilot training programme that is scheduled to begin in May 2016.

The RTN currently operates two Chinese-made Pattani-class OPVs, HTMS Pattani (511) and HTMS Narathiwat (512), commissioned in December 2005 and April 2006 respectively, and one indigenously produced modified River-class OPV, HTMS Krabi (551), that has been built to a BAE Systems design. Krabi was commissioned in August 2013.

The service is also anticipating the delivery of a second modified River-class OPV, the contract for which was announced in January 2016.

According to Airbus Helicopters, the H145Ms being supplied to the RTN have been equipped for a range of military missions that include search-and-rescue (SAR), reconnaissance, and medical evacuation operations.

The platform also features a weather radar system, cargo hooks, and an internal long-range fuel tank system. The 202 Squadron confirmed that the platform has been fitted with two machine gun pedestals, one each on the port and starboard doors.

IHS Jane’s All the World’s Aircraft lists the H145M as having a maximum take-off weight of 3,585 kg and a maximum underslung payload of 1,500 kg. The aircraft can attain a service ceiling of 6,095 m and a maximum rate of climb of 20,000 ft/min.

All five airframes are expected to be handed over to the RTN by September 2016.

Royal Thai Navy Pattani-class OPVs

A0111894811053192534HTMS Pattani (511) 

His Thai Majesty’s Ship (HTMS) Pattani was the first of two such vessels ordered from China Shipbuilding in 2003. The classification of these ships is confused, as they are sometimes called Offshore Patrol Vessels (OPV), but possibly they are too heavily armed for that appelation, and frequently called frigates, but possibly their displacement is closer to that of a corvette. The Thai Navy’s Pattani-class OPV bears a resemblance to the subsequent Chinese Type 056 corvette / light frigate, though the later is up-gunned relative to the the Thai OPV, with four YJ-3/C803 ASM and a FL-3000N RAM launcher aft, while the former has a much taller superstructure.

The Pattani is an interesting example of how Chinese hulls can be integrated with Western, sensors and weapons systems. Not much has been heard about its performance or build quality, but both were said to be better built than the older Chinese frigates.

RuNAVY to get Zircon (3M-22) newest hypersonic antiship missiles for upgraded Oscar-II class subs in 2020


SSGN Oscar II Class

As a cruise-missile submarine, the Oscar was designed primarily to attack NATO aircraft carrier battle groups. To cope with its resource problems, the Russian Navy, in the early 1990s, made an effort at preserving its core submarine force capabilities. The Russian Navy continued to invest in new construction. In the late 1990s it completed several new submarines of the third generation Oscar II. 11 of the larger Oscar II submarines were built between 1985 and 1999 at the Sevmash yard in Severodvinsk. Three have been decommissioned and one, the Kursk, sank. Two Oscar II submarines are active with the Northern Fleet and five with the Pacific Fleet.

The submarine is equipped with 24 SS-N-19 Granit (NATO codename “Shipwreck”) cruise missiles with a range of 550km. The missile has a length of 10.5m and weighs 6.9t with a warhead weighing 1,000kg. Its speed is Mach 1.5. Under the START treaty, nuclear warheads for these missiles have been replaced with high explosive warheads. The missiles, which are launched while the submarine is submerged, are fired from tubes fixed at an angle of approximately 40°.

SS-N-19/3K45 Shipwreck (Granit)


In 1969, work began on a successor to the P-500, which would emerge as the “P-700 Granit” (NATO “SS-N-19 Shipwreck”). The concept was that the P-700 would be guided to its target directly from the satellite network after a mass underwater launch from a group of OSCAR I and OSCAR II submarines, each with 24 missiles, working in conjunction with Tu-22M antiship bombers. The submarines would receive initial targeting coordinates from a longwave communications link to ground bases, launch from a range of about 500 kilometers (310 miles) at a depth of about 30 meters (100 feet), and then depart at high speed. Five submarines launching together could fire 120 missiles, overwhelming carrier group defenses and giving a high probability of “kills” even with conventional warheads.

The guidance and attack scheme used by the P-700 is very similar to that used by the P-500: one missile in the salvo of 24 goes to high altitude and “leads” the rest using active radar seeker mode, while the others stay at low altitude and remain in passive guidance mode. The active seeker is only used in short “peeks” to reduce the chance of interception. High altitude speed is Mach 2.5, while low-altitude speed is Mach 1.5. The missile carries a deception jammer system to enhance penetration of enemy defenses; has a maneuvering guidance system that can follow one of a set of different preprogrammed courses to make its attack less predictable, and can receive guidance updates in flight; and has armor over its vital systems to help thwart carrier-group close-in defenses.


As with the P-500, no images of the P-700 were released until well after the fall of the USSR, and the general belief in the West was that it was an evolutionary descendant of the P-5 / P-35 / P-6. When images were finally released, it turned out to be almost completely unrelated in configuration, with a fuselage like a fat cigar, a jet inlet in the nose, twin delta wings, and cruciform tail surfaces. The P-700 can carry a 750 kilogram (1,650 pound) conventional warhead or a nuclear warhead with a yield of hundreds of kilotonnes. It is of course much more sophisticated, in particular featuring a digital processor with three CPUs. Source craymond.no-ip.info

Russia to equip nuclear-powered Oscar-class submarines with Kalibr cruise missiles

The Russian Navy’s Project 949A Oscar-class submarines will be rearmed with the 3M-54 Kalibr cruise missile, Russia’s Deputy Defense Minister Yuri Borisov said on March 6.

“The Zvezda shipyard is carrying out profound modernization of Project 949A nuclear submarines, including the replacement of armament with the Kalibr missile complex and also the replacement of navigation, life support and other systems,” news agency TASS reported Borisov as saying.

Russia is currently in the process of upgrading the nuclear-powered Project 949A submarines to ensure they remain operational for the next 15 to 20 years.

The Kalibr cruise missile the submarines will be fitted with is a long-range cruise missile that is said to be capable of carrying nuclear warheads.

The missile has land-attack, anti-ship and anti-submarine variants and was already tested aboard Gepard class frigates and Buyan-M class corvettes against targets in Syria.

On December 8, 2015, Russian Navy’s improved Kilo-class, Project 636 submarine, Rostov-on-Don fired the Kalibr missile for the first time from a submerged position in the Mediterranean Sea.

Project 949A submarines displace some 24,000 tons when submerged and currently carry 24 P-700 Granit anti-ship cruise missiles and six torpedo tubes.

Russia built a total of 11 Project 949A submarines between 1985 and 1999. Eight submarines in the class are still in service and it is not clear how many of them will undergo the refit program. Head of the Russian Rubin design bureau told reporters in 2016 that not all of the eight boats would be upgraded. Only Irkutsk and Chelyabinsk are currently being refitted. Source navaltoday.com

The tubes, arranged in two rows of twelve, are each covered by six hatches on each side of the sail, with each hatch covering a pair of tubes. The launchers are placed between the inner pressure hull and the outer hydrodynamic hull.

The torpedo tubes fire both torpedoes and shorter range anti-ship missiles, and a combination of some two dozen weapons are carried including the SS-N-16 missile. The SS-N-16 has a range of 50km and is powered by a liquid fuel turbojet engine. It can carry either an explosive warhead or a Type 40 torpedo.

In the 1980s the Rubin Design Bureau was responsible for developing a number of third-generation nuclear submarines with cruise missiles, including Projects 949 (“Granit”, “Oscar I”) and 949A (“Antey”, “Oscar II”). The Bureau took the lead in using naval cruise missiles, designing the first cruise missile nuclear submarine – Project 659 (“Echo I”), then Project 675 (“Echo II”) and related modifications.
