ATAGS: Indigenous artillery gun sets new record in range

The advanced towed artillery gun system (ATAGS) has set a world record in terms of range by hitting targets at distance of 48 km during trial firings at Pokhran, Rajasthan.

The record of longest ever distance of 48.074 km was achieved by ATAGS with special ammunition high explosive – base bleed” (HE – BB) developed by Kalyani Group.

ATAGS

ATAGS is fully indigenously developed by DRDO and private sector consortium consisting of Bharat Forge Limited of Kalyani Group, Tata Power Strategic Engineering Division and Mahindra Defence Naval System along with Ordnance Factory Board. in mission mode as a part of the Army’s artillery modernisation programme. It is a 155mm, 52 calibre towed artillery gun.

The Armament system of ATAGS mainly comprises a barrel, muzzle brake, breech mechanism and recoil mechanism to fire 155 mm calibre ammunitions. It has a longer firing range of 40 Kms with accuracy and precision and provides greater fire power. It is also has night firing capability in direct fire mode.

ATAGS has several significant advance features, including an all-electric drive, high mobility, quick deployability, auxiliary power mode, advanced communication system, andautomated command and control system. It has a six round magazine, instead of a standard three round one. It weighs slightly more than normal due to the larger chamber.

IAF successfully conducts development trials of Astra missile

The Indian Air Force (IAF) successfully conducted developmental trials of indigenously developed Astra beyond visual range air-to-air missile (BVRAAM) over the Bay of Bengal, off the coast of Chandipur in Odisha.

Total of seven trials of Astra BVRAAM were conducted in various missions and two of them were against Pilotless Target Aircrafts (PTA) successfully fired from Sukhoi-30 MKI aircraft. They were final development flight trials of the missile, paving way for its early induction into IAF.

Astra Missile

Astra is air to air beyond visual range air-to-air indigenously developed by DRDO. It is one of the smallest weapon system developed by DRDO, having length of 3.8-metre and weighing 154kg. It is single stage solid fuelled missile and has payload capacity of 15 kg conventional explosives.

It can be launched from different altitudes and is capable of engaging targets at varying range and altitudes at both short-range targets (up to 20 km) in tail-chase mode and long-range targets (up to 80 km) in head-on mode. It is radar homing supersonic missile having maximum speed of Mach 4 (four times speed of sound).

It possesses high Single Shot Kill Probability (SSKP) making it highly reliable. It is all-weather missile with active radar terminal guidance, excellent electronic counter-counter measure (ECCM) features, smokeless propulsion and process improved effectiveness in multi-target scenario.

It has advance on-board electronic counter-measures that jam radar signals from enemy radar, making tracking of the missile difficult. It is fitted with terminal active radar-seeker and an updated mid-course internal guidance system that helps missile to locate and track targets.

The missile can be integrated with all fighter aircraft of IAF including Sukhoi-30 MKI, Mirage-2000, MiG-29, Jaguar and the Tejas Light Combat Aircraft (LCA).
