BANGKOK, Feb. 15 (Xinhua) – A Thai air force pilot was seriously injured after he jettisoned himself from an Alpha Jet trainer plane in northeastern Thailand on Wednesday.

Air force spokesman Pongsak Semachai identified the pilot as Sukhothai Srisomsai, who was found lying on open ground in Loei province, about 520 kilometers northeast of Bangkok. Local villagers scrambled to send the injured pilot to hospital.

Sukhothai, who was flying as the second pilot, instantly ejected himself from the two-seater Alpha Jet plane as he was helping the first pilot, identified as Flying Officer Puri Chulapallop, with a flying exercise aboard the French/German-built trainer aircraft.

However, the trainee pilot stayed aboard and managed to fly the Alpha Jet plane safely back to Air Wing 23 in Udorn Thani province, where both air force officers are based, according to the air force spokesman.

Air force officers at the northeastern air wing are yet to investigate the possible cause which immediately made the trainer pilot jettison himself off, Pongsak said.

Last month, an air force pilot was killed when a JAS-39 Gripen jet fighter crashlanded at Hat Yai airport in southern Thailand during an air show watched by hundreds of children on the National Children’s Day.

The pilot, identified as Dilokrit Pathavi, did not jettison himself from the Swedish-made fighter which had immediately swooped down seconds before the crash.

The Alpha Jet was designed in the late 1960s to meet a joint Franco-German requirement for a jet trainer and light attack aircraft. It was seriously delayed by the formation of multi-national production programmes for both the aircraft and its two powerplants, so that although the prototype flew on 26 October 1973, the type did not enter service for a further six years.

   The two original partners bought 350 aircraft. France received 176 E (Ecole, or trainer) versions while West Germany received 175 A (Appui, or attack) models equipped with an advanced nav/attack system, as well as a ventrally-mounted 27-mm Mauser cannon pod.

   Exports of new-build trainers were made to Belgium (33), Egypt (Alpha Jet MS1 models), Ivory Coast (7), Morocco (24) Qatar (6), Nigeria (24) and Togo (5). Egypt later procured 15 MS2 attack variants with improved avionics that included a TMV630 laser rangefinder; seven MS2s were also supplied to Cameroon.

   With the thawing of the Cold War and the transfer of German fast-jet crew training to the USA, the Luftwaffe retired its Alpha Jet fleet from 1992. Of these, 50 were supplied to Portugal in 1994, while Thailand received 25 in 2000 to replace OV-10 Broncos in the counter-insurgency and border patrol roles.

Boeing received $12.3 million contract from US Navy & Nine Allies for Harpoon Missiles

Boeing to Provide US Navy, Nine Allies With Harpoon Missile Spares

06:54 14.02.2017

Boeing has received a $12.3 million US Navy contract to provide stand-off attack missiles for the US Navy, Saudi Arabia, Australia, Japan, Taiwan, Thailand, Turkey, Malaysia, Canada and India, the US Department of Defense announced.

WASHINGTON (Sputnik) — The spares are also being sold to Saudi Arabia, Australia, Canada, Japan, Malaysia, Turkey, India, Taiwan and Thailand, the Defense Department explained.

“The Boeing Company [of] St. Louis, Missouri, is being awarded a $12.3 million… contract for the procurement of spares in support of Harpoon and Stand-Off Land Attack Missile-Expanded Response (SLAM-ER) for the Navy,” the announcement stated on Monday.

The missiles are being sold to the US allies under the Foreign Military Sales program, the announcement added.

AGM-84 Harpoon, SLAM, SLAM-ER


The Harpoon missile provides the Navy and the Air Force with a common missile for air, ship, and submarine launches. The weapon system uses mid-course guidance with a radar seeker to attack surface ships. Its low-level, sea-skimming cruise trajectory, active radar guidance and warhead design assure high survivability and effectiveness. The Harpoon missile and its launch control equipment provide the warfighter capability to interdict ships at ranges well beyond those of other aircraft.

The Harpoon missile was designed to sink warships in an open-ocean environment. Other weapons (such as the Standard and Tomahawk missiles) can be used against ships, but Harpoon and Penguin are the only missiles used by the United States military with anti-ship warfare as the primary mission. Once targeting information is obtained and sent to the Harpoon missile, it is fired. Once fired, the missile flys to the target location, turns on its seeker, locates the target and strikes it without further action from the firing platform. This allows the firing platform to engage other threats instead of concentrating on one at a time.

An appropriately configured HARPOON can be launched from an AERO-65 bomb rack, AERO-7/A bomb rack, MK 6 canister, MK 7 shock resistant canister, MK 12 thickwall canister, MK 112 ASROC launcher, MK 8 and MK 116 TARTAR launcher, or submarine torpedo tube launcher.

The AGM-84D Harpoon is an all-weather, over-the-horizon, anti-ship missile system produced by Boeing [formerly McDonnell Douglas]. The Harpoon’s active radar guidance, warhead design, and low-level, sea-skimming cruise trajectory assure high survivability and effectiveness. The missile is capable of being launched from surface ships, submarines, or (without the booster) from aircraft. The AGM-84D was first introduced in 1977, and in 1979 an air-launched version was deployed on the Navy’s P-3 Orion aircraft. Originally developed for the Navy to serve as its basic anti-ship missile for fleetwide use, the AGM-84D also has been adapted for use on the Air Force’s B-52G bombers, which can carry from eight to 12 of the missiles.

The AGM-84E Harpoon/SLAM [Stand-Off Land Attack Missile] Block 1E is an intermediate range weapon system designed to provide day, night and adverse weather precision strike capability against high value land targets and ships in port. In the late 1980s, a land-attack missile was needed. Rather than design one from scratch, the US Navy took everything from Harpoon except the guidance and seeker sections, added a Global Positioning System receiver, a Walleye optical guidance system, and a Maverick data-link to create the Stand-off Land Attack Missile (SLAM). The AGM-84E uses an inertial navigation system with GPS, infrared terminal guidance, and is fitted with a Tomahawk warhead for better penetration. SLAM can be launched from land-based or aircraft carrier-based F/A-18 Hornet aircraft. It was employed successfully in Operation Desert Storm and UN relief operations in Bosnia prior to Operation Joint Endeavor.


The SLAM-ER (Expanded Response) Block 1F, a major upgrade to the SLAM missile that is currently in production, provides over twice the missile range, target penetration capability, and control range of SLAM. SLAM-ER has a greater range (150+ miles), a titanium warhead for increased penetration, and software improvements which allow the pilot to retarget the impact point of the missile during the terminal phase of attack (about the last five miles). In addition, many expansions are being made to improve performance, survivability, mission planning, and pilot (man-in-the-loop) interface. The SLAM-ER development contract was awarded to McDonnell Douglas Aerospace (Now BOEING) in February of 1995. SLAM-ER achieved its first flight in March of 1997. All Navy SLAM missiles are currently planned to be retrofitted to SLAM-ER configuration. About 500 SLAM missiles will be converted to the SLAM-ER configuration between FY 1997 and FY 2001.

Japan and Thailand drafting legal framework on weapons and technology transfer

Japan and Thailand mull pact on weapons transfer: The Nation Columnist

Kavi Chongkittavorn (The Nation/Asia News Network)

BANGKOK (THE NATION/ ASIA NEWS NETWORK) – Japan is currently drafting a legal framework with Thailand to allow the future transfer of its defence equipment and technology. If that happens soon, it would represent a significant milestone in their mutual defence cooperation since the end of World War II.

Thailand collaborated with Japan during World War II, but turned around at the end of war and sided with the allied forces. Both countries are now part of the United States-dominated alliance.

During the Vietnam conflict, the US maintained over 100,000 troops and hundreds of aircraft in Thailand as its forward bases to counter the threat of communism.

After the end of the Cold War, Thailand’s strategic value was not given serious attention by the Americans and the evaluation gradually eroded the once unshakeable US-Thai alliance. The trend has been a blessing in disguise as other powers used this window to fill the vacuum.

Doubtless, Japan’s proposal quickly received unanimous support from the Thai Ministry of Defence and National Security Council, when the idea of weapons and technology transfer was broached early this month.

It is an open secret that Bangkok has constantly complained that the US government has not paid any attention whenever Thailand, as a non-Nato ally, wanted to procure additional weapons to beef up defence and overall capacity. Washington often responded with a long list of conditions. Notably, it is the only US ally that does not have ministerial-level strategic consultations that include foreign and defence ministers.

With Japanese Prime Minister Shinzo Abe’s proactive foreign and security policies toward Southeast Asia now firmly in place, Thailand is more confident and enthusiastic to increase its engagement with Japan.

Both sides are hoping the final framework will be ready for signature by the middle of the year. This dramatic development has been accelerated by the current fluid strategic landscape. Furthermore, Tokyo needs an additional defence tier beyond the US-Japan security framework that would strengthen its national security in this neighbourhood.

More than the Thai and Japanese officials would like to admit, they share a similar anxiety and concern that the new US administration and foul-mouthed President Donald Trump could cause further damage to the current alliance system in the Asia-Pacific. Any disruption, real or imagined, to security networks operational since World War II, would impact on the regional strategic landscape. Japan would be the most vulnerable.

Japan has a large stockpile of used but well-maintained defence equipment such as jet fighters, frigates, artillery and other hardware, which could be transferred to Thailand at a moment’s notice.

Thai and Japanese defence officials share the same guidelines and interoperability of US-manufactured weapons. During the Chuan Leekpai administration (1997-2000), repeated attempts were made to transfer some spare parts of US-made F-5 jet fighters from Japan. But they were not successful due to the lack of a legal framework and US support at the time.

All along, Japan has taken an active part in the annual joint Thai-US military exercise, Cobra Gold. The upcoming event – the 36th – will be opened by Pacific Commander Rear Admiral Harry Harris on February 14 in Sattahip, Chon Buri.

Japan has benefited greatly from the joint exercise, especially on land assaults and amphibious landings. In recent years, the exercises were concentrated on humanitarian assistance and disaster management.

Previously, Thailand has been slow in responding to Japan’s new collective self-defence postures. At the end of 2013, during the visit of Abe to Bangkok he was supposed to sign a memorandum of understanding on maritime security cooperation with then-prime minister Yingluck Shinawatra. However, before his arrival in Bangkok, Thailand notified Tokyo it was not ready to sign. Subsequently, Japan has looked towards Vietnam, the Philippines – as well as Indonesia – as the countries to enhance maritime security cooperation. The first two countries were given priority due to their urgent need to improve their maritime security capacity.

At the November meeting in Vientiane, the Asean and Japanese defence ministers held back-to-back meetings and came up with the Vientiane Vision, which details Japan’s defence cooperation initiative with Asean.

From now on, there will more dialogue and cooperation on rules of law, deepening and diversifying practical cooperation on regional security, transfer of defence equipment and technology as well as capacity building.

Japan used to be discreet in its security approach with Asean as a group and individually, knowing full well the sensitivity of past histories, especially towards the countries that fought Japan’s militarism. Now under Abe’s leadership, Tokyo has exhibited clearly the Asean-wide defence doctrine.

During the 1990s, Japan moved cautiously to establish defence exchanges with Asean members involving senior officials. Over past decades, since Japan joined Asean as a dialogue partner 1973, the focus of their relations has been on economic cooperation and investment. Japan is the main driver of economic development and progress in the region. In addition, Tokyo has also played a constructive role in bridging the gap between the new and old Asean.

Beginning in the new millennium, Asean-Japan defence cooperation was gradually transformed from military exchanges to confidence building and enhanced mutual understanding. However, the nature of their cooperation has become more strategic, involving capacity-building cooperation and technological transfer. Last year, Japan provided naval vessels to the Philippines and Vietnamese to bolster their maritime security.

In the case of Thailand, Japan has reiterated that the transfer of defence equipment and technology is strictly bilateral, serving to enhance security and defence cooperation between them. Therefore, both governments must approve any transfer or future use that involves the third party.
