State-run aerospace behemoth Hindustan Aeronautics Ltd (HAL) is looking at setting up logistics bases in Malaysia, Vietnam, Indonesia and Sri Lanka as part of initiatives to woo the countries to buy India''s light combat aircraft Tejas and military helicopters.
Chairman and Managing Director of HAL R Madhavan said the HAL is considering to build logistics bases in the four countries as they use a number of Russian-origin military aircraft and choppers whose serviceability is "very poor".
He said the HAL is now seriously focusing on boosting exports in sync with the government''s priority and identified South East Asia, West Asia and North Africa to sell key platforms like Tejas, attack helicopter Rudra and advanced light helicopter Dhruv.
Last month, Prime Minister Narendra Modi has set an ambitious defence export target of USD 5 billion dollars in the next five years and asked all the key military manufacturers to work hard to achieve the target.
"We are looking at setting up maintenance facilities in Malaysia, Vietnam, Indonesia, Sri Lanka. We can give them a lot of support to as these countries use lot of platforms which are common to India, and their serviceability is very poor," he told PTI.
The HAL top executive said the company is looking at setting up maintenance facilities in these four countries as having logistics bases is key to sell the products and ensure after-sales services.
Without divulging details, Madhavan said a number of countries in West Asia are also in touch with the HAL for possible procurement of its key products.
"We now are looking at exports very seriously. A sizeable number of countries are showing lots of interests in the platforms we are producing as they are world class. We are in talks with so many countries," said the HAL chief.
Specifically, he said that Tejas has a "very good" export potential as it is a four-and-half generation fighter jet which can compete with some of the famous military jets in its class.
The Tejas has been Developed by Aeronautical Development Agency and the HAL. The lifespan of the jet would be a minimum of 30 years just like any other frontline combat aircraft. The combat jets are classified under various generations depending on their avionics, capability and weapons systems. The current fleet of fighter jets with the IAF range from three-and-half generation to the fourth generation.
The Indian Air Force has already placed an order for 40 Tejas and is likely to seal a contract "very soon" with HAL for another 83 aircraft at a cost of around Rs 38,000 crore.
India is one of the largest importers of arms and military platforms globally. The government has been focusing significantly on promoting defence indigenisation by taking a slew of reform initiatives including liberalising FDI in defence sector.

I am more interested to see helo exports. Read recently that Vietnam was looking at Dhruv helos with some interest. Also the Brahmos export to Philippines would be a big deal, but everything has gone quiet there suddenly.Only Vietnam and Sri Lanka will be willing to buy the LCA Mk1A as is, for the other two the Israeli avionics will have to be replaced with Indian or European avionics.

The Indian Army Is Set To Procure New Version Of The Swathi Weapon Locating RadarSWATHI Weapon Locating Radar – India’s $40 Million Export To Armenia

In March 2020, India and Armenia signed a deal for the sale of four Swathi weapon locating radar (WLR) stations. This deal, worth $40 million was the first of its kind with Armenia, and stands out because vendors from Russia and Poland were also in the running.
A WLR is designed to detect the trajectory of an artillery shell. Using the detected path, one can narrow down on an enemy artillery fire base, and direct return fire to successfully destroy it. The Swathi WLR has been designed by the Defence Research and Development Organization’s (DRDO) Electronics Research and Development Establishment (LRDE) laboratory and produced by Bharat Electronics Limited (BEL).
Here’s an interesting fact – the Swathi WLR is a derivative of the fire-control radar system used on board an Akash surface-to-air missile. While testing the missile, engineers observed that the Akash’s FCR (called the Rajendra radar) could also track artillery shells being fired in a range nearby, and therefore used the same design while developing the Swathi.

Here’s all you need to know :
Adreesh Ghoshal is an automobile engineer with a deep interest in defence technology. He lives in Mumbai
- The first working prototype was ready in 2004 as part of an INR 20 crore contract issued by the Ministry of Defense in 2002.
- In 2008, the Ministry of Defense ordered 30 Swathi WLRs as part of an INR 1,600 crore contract signed with the Defense Research and Development Organization & Bharat Electronics Limited.
- The radar array is designed to detect and track incoming artillery rounds, mortar rockets and the launchers
- It can also provide fire correction by tracking friendly counter-battery fire
- Large calibre artillery rounds (105 mm & 155mm) can be tracked from a distance of 30km.
- The WLR utilizes a C-Band radar with a frequency range of between 4 – 8 GHz and a wavelength span of 3.75 and 7.5 cm
- The radar is mounted on an 8-wheeled Tatra truck, a vehicle that has multiple uses in various departments of Indian defence forces.
- The Swathi WLR is a passive electronically-scanned array radar, which means that the beam can automatically lock on to a target without having to move the transmitter.
- The transmitter/receiver is fixed, and so is the antenna.
- The Swathi WLR has an azimuth range (rotation around a vertical axis) of -45 to +45 degrees, and an up-down slew-able range of -135 to +135 degrees.
- The radar can track rounds fired at both low and high angles, and at all aspect angles – from behind or towards the radar, or at an oblique angle to the array.
- This change in direction takes only 30 seconds, because it’s done electronically.
- The radar is of a coherent type, which helps clear out the background clutter (trees, buildings etc are not tracked).
- This capability is achieved via the CFAR (Constant False Alarm Rate) which sets a threshold for how weak or strong a received signal should be, thereby reducing the risk of a false alarm.
- The resolution of the signals is improved using pulse compression.
- The high-power signals are generated with the help of a Travelling Wave Tube, which is an oscillator with protection from power surge and integrated cooling systems.
- The Swathi Weapons Locating Radar can operate between temperatures of -20 and +55 degrees.
- The on-board map can store a map spanning 100 x 100 km, with locations of up to 99 tracked targets.
- Up to 7 targets can be tracked simultaneously.
- The radar is designed to be fully operational within 30 minutes from being set-up.
- Interestingly, while designing a copy of the AN/TPQ-37, the Chinese noticed that the radar’s accuracy went down in hot and humid conditions,
- This became worse when operating in a coastal region or in an area prone to heavy showers in the monsoons.
- Another limitation of the AN/TPQ-37 was that it had a difficulty tracking shells following a flat trajectory.
- Compared to the Raytheon-built AN/TPQ 36-37 series, the Swathi WLR can operate at a much higher altitude of 16,000 feet, making it perfect for deployment in the LOC and the LAC.
