The vessel is intended to conduct routine patrols, border control and fishery protection missions in Thailand’s exclusive economic zone (EEZ) and can also be deployed to perform disaster relief operations and natural resources protection in the Gulf of Thailand and the Andaman Sea.

Krabi-class vessels construction

BAE Systems signed a technology transfer agreement with Bangkok Dock to supply the 90m offshore patrol vessel design for the construction of HTMS Krabi in Thailand in June 2009.

Keel laying ceremony of HTMS Krabi (551), worth THB2.8bn (approximately $79.2m), was held in August 2010 and the vessel was launched at Mahidol Adulyadej Naval Dockyard in November 2011. It was inducted into the RTN’s service in August 2013 and has completed 1,000 days of operation at sea.

HTMS Krabi took part in the International Fleet Review 2013 organised by the Royal Australian Navy in Sydney Harbour, Australia, in October 2013.

In January 2016, BAE Systems received a contract from Bangkok Dock to provide design and engineering support for the second 90m offshore patrol vessel, which is estimated to cost THB5.5bn (approximately $155m).

Design and features of Krabi vessel

HTMS Krabi

The design of HTMS Krabi vessel is based on 90m offshore patrol vessel, an evolution of the 80m River-class offshore patrol vessel (OPV), which is designed and built by BAE Systems for the UK Royal Navy.

HTMS Krabi is 90.5m-long, 13.5m-wide and 7.7m-high, and has a draft of 3.8m. With a displacement of 1,969t, the vessel can accommodate up to 39 crew members plus 50 embarked personnel.

USAF wants on-time F-X, not more F-22s

 

09 March, 2016 BY: James Drew Washington DC

The US Air Force has no interest in restarting production of the Lockheed Martin F-22, partly because it’s too expensive and because it wants to move quickly on a next-generation fighter.

The service’s deputy chief of staff for strategic plans and requirements said as much during a congressional hearing on 8 March, suggesting that fighter jet manufacturers like Boeing, Northrop Grumman or Lockheed Martin may decide to offer modifications to existing technologies and platforms in the next F-X competition.

“Because we want to do it faster and don’t want to do another 20-year development programme for a whole host of reasons, we’ll try and go with technology that are at a high readiness level now with manufacturing capabilities that are at a high readiness level now,” Lt Gen James Holmes tells a Senate Armed Services subcommittee panel in response to questions about restarting F-22 production.

“I think it’s completely possible as we get the requirements that there may be competitors that bid on modification of an existing technology or platform like the F-22 and the F-35.”

Industry sources tell Flightglobal that there has been a lot of interest within the Pentagon recently about the restarting F-22 assembly. However, air force leaders have repeatedly denied seeking rough-order-of-magnitude cost estimates for procuring more F-22s and instead point to future fighter concepts as the best way forward.

The 187th and last twin-engine Raptor rolled off the assembly line in Marietta, Georgia in December 2011, but the manufacturing equipment was stored for possible use later. A RAND study in 2010 placed the cost of resuming F-22 production at $17 billion in 2008 dollars for 75 more aircraft, or $267 million per jet.

“There were some initial rough order of magnitude estimates of what it would cost,” USAF military deputy for acquisition Lt Gen Arnold Bunch tells the subcommittee. “[But] we have not estimated what it would be to re-open the line and populate it with more modern technology. We’ve not done that at this time.”

Holmes says pressing forward with the air force’s Next-Generation Air Dominance programme is the better way to make up for lower-than-planned fifth-generation fighter capacity, but cannot be a technologically exotic fighter jet that takes two or three decades to develop.

“They cost too much, they take too long, they make you drive for technology that’s so far into the future that it’s really hard to achieve and by the time you spend 30 years achieving it, it may not be exactly what you want,” he explains after the hearing. “We’re trying to move to a world where we go forward with new airplanes that take advantage of technology that’s ready to manufacture and we have the manufacturing skills to do it, and what could we produce in five years or 10 years instead of 30 years?

“It’s purely speculation on my part, but if I was going to ask a company to bid on what they could build for me in five years or 10 years, I’d expect that some of them would take advantage of work they’ve already done and base it on something they already have.”

Similar thinking has led Lockheed to propose an upgraded version of the KAI T-50 for the air force’s T-X trainer programme over a clean sheet design proposed by Skunk Works. Boeing and Northrop, though, do not have any in-service fifth-generation fighters upon which to base F-X proposals.

The US Navy is already moving forward with an analysis of alternatives (AOA) for its F/A-XX strike fighter platform that will eventually succeed the Boeing F/A-18 Super Hornet. The air force will begin that acquisition process next year, says Holmes.

The Air Force Research Laboratory is already working with industry on new aircraft and engine designs. Boeing, Northrop and Lockheed have already started releasing artist’s impressions of conceptual “sixth-generation” fighter jets, but none are based on previous aircraft.

Pakistan reluctant to buy fifth generation warplanes: PAF

 

The News International

April 08, 2016

PARIS: Pakistan wants to upgrade its ageing fleet of fighter jets in anticipation of a prolonged battle against Islamist militants, although the purchase of fifth-generation planes would only be a last resort, a senior air force official said.

US ally Pakistan, a nuclear-armed nation of 180 million people, is fighting a Taliban insurgency in its northwest, a separatist insurgency along its Iranian border in the west, and has a heavily militarised and disputed border with arch rival India in the east.

“Our concern is that we don’t know how long these anti-terrorist operations will continue,” Pakistan Air Force second-in-command Muhammad Ashfaque Arain told Reuters in an interview late on Wednesday.

“We have weakened them (militants) to a great extent, but I don’t see an end in the very near future, so all the burden is being shared by the F-16s and its pilots. Sceptics suspect that Pakistan’s military is seeking an improved arsenal to counter the growing military might of India,” he said.

To fill the void, Islamabad has decided to bet on the JF-17 fighters, jointly developed by China and Pakistan, rather than spending billions on fifth-generation multi-role aircraft like Dassault’s Rafale, which rival India is buying, or the Russian Su-35.

That option, Arain said, had almost been ruled out for being too expensive and because Pakistan did not want to mix technologies and resources.It would only be reconsidered if “it was pushed against a wall”.

Instead, 16 JF-17s will be produced this year with a further 20 in 2017, but Arain acknowledged that the jets’ usefulness in current operations was limited because they lack precision targeting. “Operationally, the aircraft are working pretty well so if we had a targeting pod on the JF-17, the burden would be shared,” Arain said, adding that his visit to Paris was in part aimed at assessing from French officials the prospects of supplying the Thales-made Damocles, a third-generation targeting pod. He said that was Islamabad’s priority for now.

“We’re looking at the best option. The Damocles is a battle-proven system and the other options are not,” Arain said. “If we do not get the Damocles pod for example, we will need to look for alternative options that may not be proven. In the long run, the air force was thinking about its needs beyond 2030 when F-16s and JF-17s would start to be replaced.”

The United States in February approved the sale to Pakistan of up to eight F-16 fighter jets for the short term, but Arain said even that was proving complicated. “It’s a much cheaper fighter jet, but buying more F-16s is economically not feasible for us and then there is a lot of human outcry,” he said.

Arain countered any suggestion that Pakistan might want greater air power to target India by saying that New Delhi itself was expanding its fleet. “We get eight aircraft and there are people who start to say that it will tilt the balance of power in South Asia. But when somebody across the border buys 36 aircraft and has plans to buy 126, that doesn’t change the balance of power,” he said, referring to India.

Military Defense Industry Technology – Russian armoured vehicles

 

Published: Sunday, 27 March 2016 08:43

Analysis about the Russian armoured vehicles and tanks in the global military market.

As of early 2016, three Russian defense industry companies were suppliers of various armoured vehicles to both domestic and international markets. Scientific-research corporation Uralvagonzavod (Russian acronym: UVZ) offers T-90S, T-90MS and upgraded T-72 main battle tanks, BMP-T / Terminator-2 fire support vehicles (FSV), BMR-3M mine clearance vehicles, BREM-1M armoured repairing vehicles (ARV).

The military department of the Tractor Plants concern produces BMP-3 / BMP-3M infantry fighting vehicles (IFV), BREM-L ARVs, BMD-4M airborne infantry fighting vehicles and BTR-MDM armoured personnel carriers (APC). Military-Industrial Company (Russian acronym: VPK, a subsidiary of Bazovy Element Group) manufactures BTR-80 / BTR-80A / BTR-82 / BTR-82A APCs, BREM-K ARVs and AMN-233114 Tigr-M multi-purpose 4×4 utility vehicles. The aforementioned companies are the core of Russian armoured vehicles production.

Since 2001, the interest of foreign customers to Russian MBTs has significantly increase. According to the Stockholm International Peace Research Institute`s (SIPRI) arms transfers database, in 2001-2015, Russia exported 1,416 T-90S tanks (both ready-to-use and kits for local licensed assembly) of 2,316 ordered MBTs. The T-90S local production lines were established in India and Algeria. India still remains the most substantial foreign operator of Russian T-90S tanks. Within the prescribed period, this country received 947 MBTs (including 761 locally assembled from kits supplied by UVZ).

As of early 2016, Russia had to supply approximately 710 T-90S tanks to India. Algeria got about 315 T-90SA tanks (“A’ stands for Algerian) equipped with improved air conditioning unit. The North African country is to assemble about 190 MBTs. In early 2016, Russia almost finished the deliveries of 100 T-90S tanks equipped with Shtora-1 optical-electronic jamming system to Azerbaijan. Ten MBTs of such type were supplied to Turkmenistan in 2009-2012. Uganda received 44 T-90S tanks in 2011. 

Since 2001, the interest of foreign customers to Russian MBTs has significantly increase. According to the Stockholm International Peace Research Institute`s (SIPRI) arms transfers database, in 2001-2015, Russia exported 1,416 T-90S tanks (both ready-to-use and kits for local licensed assembly) of 2,316 ordered MBTs.Russian-made T-90S main battle tank at RAE 2015 defense exhibition in Nizhny Tagil, Russia.

T-90S and its modification still remain in high demand by perspective foreign customers. During the Russia Arms Expo 2015 (RAE-2015) several Arabic states revealed their keen interest to the acquisition of T-90S and T-90MS tanks. When the coalition led by Saudi Arabia started intervention to Yemen to fight Housit rebels, Western-originated armoured vehicles were found to unreliable and not able to effectively fight in desert and desert-mountain regions. According to several reports, the chassis AMX-56 Leclerc MBTs deployed by United Arab Emirates faced with several technical difficulties during the intervention, while Leclerc revealed its high firepower performance. Saudi Arabia deployed at Yemen the US-originated M1A2 Abrams tanks. Houthis eliminated several M1A2s, using ageing Soviet 9M111 Fagot (NATO reporting name: AT-4 Spigot) and 9M113 Konkurs (AT-5 Spandrel) anti-tank guided missiles (ATGM).

In such conditions, the Arabic nations have shown their interest to the potential acquisition of T-90MS, the latest modification of T-90S. It retains the high serviceability and maintainability of its predecessor, while the tank`s firepower and protection have been significantly increased compared to basic T-90S. T-90MS has received Relict explosive reactive armour (ERA) system developed by NII Stali. It is installed on the frontal armour plate, the sides and the turret of the upgraded MBT, increasing its survivability on the modern battlefield. As the war in Syria demonstrated, the Relict`s predecessor, Kontakt-5 (basic ERA of T-90A/T-90S) armour could successfully resist to TOW-2A/B BGM-71E and BGM-71F ATGMs. Relict is reported to be 50% more effective, than Kontakt-5. T-90MS retains 2A46M-5 gun-launcher, which could fire both standard 125mm anti-tank/anti-personnel rounds and 9M119M/9M119M-1 Invar/Invar-M1 ATGMs.

Russian IFV are also highly demanded by potential foreign customers. During the RAE-2015 show, the Arabic states revealed their interest to the latest modification of world-known BMP-3, namely, BMP-3 Derivatsiya (Derivation).Russian BMP-3 armoured infantry fighting vehicle at military parade in Moscow (Source Wikimedia)

Russian IFV are also highly demanded by potential foreign customers. During the RAE-2015 show, the Arabic states revealed their interest to the latest modification of world-known BMP-3, namely, BMP-3 Derivatsiya (Derivation).

In 2001-2015, Russia delivered BMP-3 / BMP-3M armoured vehicles to the foreign customers. Azerbaijan got about 100 upgraded BMP-3M IFVs. Indonesia received 54 BMP-3Fs in naval configuration for the national Marine Corps. The deliveries of 70 upgraded BMP-3Ms to Kuwait had been finished by end-2015. South Korea received 37 BMP-3s in basic configuration in 2005-2006. Six BMP-3s were supplied to Turkmenistan. Venezuela had received 123 BMP-3Ms and BREM-L ARVs by end-2015.

Basic BMP-3 / BMP-3M has an outstanding firepower, estimated to be the best in its class. The vehicle is equipped with 100mm 2A70 gun-launcher, which could fire 3UOF17 and 3UOF19 high-explosive (HE) shells and 9M117 Bastion (AT-10 Stabber/AT-12 Swinger) ATGMs, and with 30mm 2A72 automatic gun. Such combination allows to effectively support dismounted troops on the modern battlefield. Basic BMP-3 lacks side armour (compared to Western analogues), but the installation of additional armour plates and Kaktus ERA provide sufficient protection from small-caliber automatic guns and ATGMs. BMP-3 could be upgraded with Arena-E active protection system (APS).

At the same time, NATO nations are developing new small-caliber (up to 40mm) guns, which could penetrate over 100 mm of steel armour, using kinetic projectile (not shape-charge warheads). In 2014, CTA International company developed 40mm 40 CTAS (CT cannon). It fires advanced armour-piercing fin-stabilized discarding sabot – tracer (APFSDS-T) rounds, being able to pierce more than 140mm of rolled homogeneous armour (RHA) at 1,500 m. Such shell can penetrate the armour protection of light armoured vehicles, IFVs and even side armour plates of modern MBTs. The newest Western IFV (for instance, British Ajax and French VBCI) can be armed with CT cannon. At the Eurosatory-2014 defense show, French Nexter Group demonstrated T40 manned combat module armed with 40 CTAS. T40 module is intended for installation on VBCI IFV. It can also be adapted for other Western armoured fighting vehicles (both tracked and wheeled).

As a response to 40 CTAS cannon, Russian Tractor Plants concern developed BMP-3 Derivatsiya IFV. It is armed with 57mm naval cannon chambered for 57x348mm round. The APFSDS round fired from such cannon could easily penetrate 130-140mm of RHA at distances up to 1,800-2,000m. Hence, 40 CTAS is not the only available “small caliber-high power” IFV gun at the international arms market. Russian 57mm cannon is also effective against low-flying aerial targets and personnel (using HE round).

About 318 basic BTR-80 were supplied to Bangladesh. Russian-made BTR-80 8×8 APC Armoured Personnel Carrier at Defense Exhibition near Moscow, Russia.

The export of BTR-80 / BTR-80A / BTR-82 / BTR-82A APCs within the prescribed period was huge despite the weak armour and anti-mine protection of the vehicles. The BTR-80A/82A APCs were demanded due to high power (unlikely Western analogues, both carriers are armed with extremely effective 30mm 2A72 automatic cannon). In 2001-2015, Russia delivered to foreign customers 1,036 of APCs of 1,068 ordered. Azerbaijan received 70 BTR-80As. About 318 basic BTR-80 were supplied to Bangladesh. Belarus ordered 32 BTR-82A APCs. Colombia got eight BTR-80 in Caribe configuration. Eight BTR-80 carriers were supplied to Djibouti. Indonesia received 12 BTR-80A. About 93 BTR-80A, 44 BTR-82A and 18 BTR-80 APCs were delivered to Kazakhstan. Mongolia received 20 BTR-80s under Russian military aid program. North Korea got 32 BTR-80As in 2000-2001. Approximately 19 BTR-80As were delivered to Sri-Lanka. Sudan got 90 BTR-80A APCs designated as Shareef-1 in Sudanese service. Eight BTR-80As were supplied to Turkmenistan. Uganda received 32 BTR-80As. About 50 basic BTR-80s were sold to Uzbekistan. Venezuela got 114 BTR-80As. About 100 BTR-80A APCs were supplied to Yemen.

The interest of foreign customers to BTR-80A / BTR-82A will be stable in the years to come, as it is a relatively inexpensive, reliable and effective APC, being able to deliver sufficient firepower to dismounted soldiers. BTR-80A / BTR-82A has an IFV firepower in an APC form-factor. The installation of spall liner and anti-blast seats on BTR-82A increases its protection from small-caliber arms, heavy splinters and land mines. The deliveries of basic BTR-80 within the prescribed period were limited, as modern Western analogues have Level 4 STANAG 4569 protection, which can resist to 14.5mm armour-piercing bullet fired from BTR-80`s KPVT machinegun.

Air Force looking to replace A-10 Warthog

Updated 10:16 AM ET, Sat April 9, 2016

Washington (CNN)A top U.S. general says the Air Force is reviewing the future of its close air-support aircraft, a role currently filled by the A-10 Warthog, which first flew in 1975.

“My requirements guys are in the process of building a draft-requirements document for a follow-on (close air-support) airplane,” said Lt. Gen. Mike Holmes, the deputy chief of staff for strategic plans and requirements.
Holmes, who made the comments to reporters at a breakfast hosted by the Air Force Association on Thursday, said the Air Force would use these combat requirements to determine what type of aircraft would best meet its needs. Potential options could include building an entirely new dedicated aircraft, using existing aircraft, or extending the life of the A-10 even further.
A spokesperson for the Air Force confirmed the ongoing requirements process to CNN.
The Air Force had originally planned for its version of the F-35 Joint Strike Fighter to replace the A-10 Thunderbolt, or Warthog, as it has been nicknamed. But the F-35 project has been beset by delays and cost overruns and the demands of the counter-ISIS mission have caused the Pentagon to reconsider its plans in the 2017 budget.
But Holmes’ announcement shows that the Air Force is now considering alternative replacement options.
Unlike the multi-role F-35, the A-10 is the only airplane in the Air Force specifically designed for close air support, a mission that has become urgent in the fight against ISIS.
The battle tested A-10 has seen combat in Iraq, Afghanistan and most recently in Syria where it was able to target enemy forces up close without risking friendly fire casualties because the pilots are flying slow enough to visually distinguish between enemy and friendly forces.
Rep. Martha McSally, an Arizona Republican lauded the Air Force’s decision to reevaluate its plans, calling it “a big victory.”
McSally, a retired Air Force colonel and former A-10 pilot who flew missions in Iraq and Afghanistan, told CNN she was “glad to see the (Obama) administration recognize the flaws in seeking to eliminate the A-10 before we have a tested, proven replacement.”
“As a result of our advocacy, the Air Force will begin consideration of the follow-on platform to the A-10, including upgrading our current fleet to extend its service life. This is the exact approach for which I have advocated,” said McSally, a member of the Armed Services Committee.
The A-10 can carry up to 16,000 pounds of bombs and missiles and is armed with a powerful 30 mm, seven-barrel Gatling gun, which can fire depleted uranium bullets at 3,900 rounds per minute.
Holmes added that the Air Force was trying to define exactly what was needed and that affordability would be a key consideration in determining the future of the next generation of close air-support aircraft.
The previously proposed F-35 replacement is projected to cost approximately $135 million per plane, while the unit cost of an A-10 is $18.8 million, according to a U.S. Air Force fact sheet.
Retired naval aviator Cmdr. Chris Harmer told CNN in March that using an F-35 to fly close air support against insurgents would be akin to “buying a brand new Rolls Royce to take the garbage to the dump.”
Harmer estimated the cost of flying a jet like the F-35 to be about $45,000 per hour of flight, while the A-10 costs about one-third as much to operate.
Holmes said that one possible replacement for the A-10 could be a type of already-existing turbo-propeller aircraft. Examples of this category of aircraft include the A-29 Super Tucano and AT-6 Wolverine. The U.S provided four A-29s to the new Afghan air force in January to help fight the Taliban.
U.S. Central Command, which oversees military operations in Iraq and Afghanistan, recently deployed a pair of Vietnam-era OV-10 Bronco turbo-propeller planes against ISIS as part of an experiment to see if these type of aircraft are more effective in conducting counterinsurgency operations than more modern jets like the F-35.
Because they consume less fuel and can cruise at slower speeds, these turbo prop planes can loiter over the battlefield for hours like drones, but unlike unmanned aircraft, the pilot has greater visibility of the battlefield and can see the location of enemy forces and attack them directly with machine guns and more bombs and missiles than a drone can carry.
Holmes cautioned that a final decision is still “a long way off” and that future budgets would determine what the future of the close air-support aircraft will look like.
