The mean, green Black Widow Spider armoured personnel carrier had a commanding presence at the recent Defence & Security exhibition at the Impact Arena exhibition hall, attracting sideways glances from visitors awed by its 30-millimetre automatic canon, day and night mission electro-optical camera, and its eight giant rubber-based wheels.

The military behemoth took pride of place at the event not only because its fine lines lent it a sophisticated air, but also because it is the first vehicle of its kind ever to be built by the Army.

“It started a couple of years ago when we received an order from the Defence Ministry to develop an armoured car,” said General Sompong Mukdasakul, director of the Defence Technology Institute (DTI), who was responsible for the vehicle’s development. “By doing it on our own, we will be able to produce as many as we need. We don’t have to wait in a queue like we do when ordering from overseas.”

As an experienced combat veteran who has participated in a number of battles, including the Thai-Laotian Border War, the general underlined the need for the country to have well-prepared troops. This is also to combat possible future threats like global terrorism, not to mention the possibility of having to cooperate withAsean countries in national defence technology development.

“The troops of a country are just like the security guards of a house,” he said. “If we don’t have them, we’ll be instantly invaded by thieves.”

Sompong said the DTI, which is the ministry’s research and development centre, started to forge cooperation with other parties in order to accomplish this vehicle. A Public Private Partnership (PPP) was explored to support the project, he said.

Under this cooperation platform, the organisation received cooperation from various agencies, both public and private, including safety car producer Preechataworn Industry and the National Metal and Materials Technology Centre. Research labs from educational institutions such as Chulalongkorn University and King’s Mongkut Institute of Technology Ladkrabang also contributed to the vehicle’s research and development.

Some foreign agencies also took part in the project, the general said, but he insisted their identities had to be kept confidential.

Still, the DTI claims to have been responsible for 60 per cent of the technologies used to develop the vehicle. Sompong referred to the development as a “breakthrough” for the country’s automobile industry.

The DTI and its partners built the vehicle in a short period of time compared with the time it usually takes other countries, Sompong said. It usually takes more than a decade for other countries to achieve the same scale of work as they have to adhere to the North Atlantic Treaty Organization (NATO) Standardization Agreement.

When comparing costs and benefits, the general said imported and domestically-made armoured cars are not highly different in price, with both costing around Bt40 million baht. However, domestically-made armoured cars are more worthwhile considering long-term maintenance and further development.

What is vital, Sompong said, is cooperation with outsiders. Cooperation with foreign agencies is beneficial not only in saving time on research, he said, but also in bringing know-how to Thai employees, resulting in long-term development of technical knowledge.

“The enhanced knowledge will provide a good stimulus to the country’s overall economy,” the general said. “And now the government is increasing the research budget by as much as one per cent of the country’s GDP. I think that’s a good sign.” Having already launched its new vehicle, the DTI plans to complete full tests and enhancements on the vehicle by next year. However, even Sompong could not predict the fate of the Black Widow Spider 8×8. “We still have to see if the Defence Ministry will approve more orders on the car,” he said.

The development of the Black Widow Spider is seen by some military observers as another step towards the country’s self-reliance of military equipment and weapons. Since its establishment in 2007, the DTI has spent its time trying to develop a range of lightweight weapons including the DTI-2 Rocket 122-mm unmanned aerial vehicle and virtual shooting range simulators.

At present, the Army spends an annual budget of around Bt1 billion in weapons development, said the general.

“Carrying out research requires a lot of time and human resources,” he said. “And our country has for a long time been static in developing new research. Mostly, we bought technologies [from other countries] but hardly developed our own. We have the illusion that we are capable while other [countries] keep passing us.”

Looking proudly at the military monster he helped to create, Sompong hinted that the organisation would reveal its upcoming project next year. “It will be a floatable one,” he said.

“We are working with the Royal Thai Marine Corps to develop a massive, floatable vehicle. We already have a draft model. The final product should be finished next year,” Sompong said.

Rafael Trophy active protection system on Oshkosh M-ATV

At AUSA 2015, Rafael Advanced Defense Systems Ltd., developer and manufacturer of TROPHY APS, the world’s only operational and combat-proven active protection system for armored vehicles, displays its lighter, TROPHY LV (light vehicle) on an Oshkosh Defense M-ATV Base (SXB) 4X4 Mine-Resistant Ambush Protected (MRAP) vehicle at AUSA, Washington DC.

The Oshkosh M-ATV is a superior MRAP (Mine-Resistant Ambush Protected) vehicle. The Rafael Trophy LV solution enables greatest level of protection, hostile fire detection and greater lethality increasing operational capabilities and allowing troops to carry out missions with greater flexibility, maneuverability and confidence.

Trophy is a family of situational awareness and active protection hard kill systems that operate in three major stages: Threat detection and threat tracking, followed by hard kill countermeasure activation and threat neutralization.

The operational requirement to equip armored vehicles with an APS is dictated by the growing proliferation of advanced Anti armor weapons. Trophy-LV has the proven capability to defeat advanced threats coupled with handling all safety considerations of an autonomous shooting system, an issue that has raised concerns among potential customers for many years

Trophy-HV has so far saved dozens of soldiers’ lives, ever since its first deployment in August 2009 and especially in operation “Protective Edge” (summer 2014), where numerous anti-armor threats were launched at Merkava IV tanks equipped with Trophy – none of these potentially lethal attacks caused casualties to IDF troops.

The downscaled Trophy-LV offers a cost-effective, 360º protection, easy integration, minimal risk of collateral damage, outstanding performance at a fraction of the weight, coupled with the highest level of kill probability.

In addition to Trophy LV, the Oshkosh M-ATV will be fitted with a Rafael Samson Remote Controlled Weapon Station (RWS). Samson provides military users with enhanced capability not only in survivability, but affording them greater lethality, derived from Trophy-LV’s hostile fire detection (HFD) capabilities, coupled with, the world’s top-of-the-line RWS, Globally integrated on thousands of fielded ground and naval platforms in over 25 countries, Rafael’s Samson family of advanced Remote Weapon Stations (RWS), capitalizes on extensive combat experience with a deep understanding of emerging military needs.
