The Advanced Towed Artillery Gun System (ATAGS) is a towed 155 mm/52 calibre howitzer that is being developed for the Indian Army by Defence Research and Development Organisation (DRDO) and manufactured by Bharat Forge. ATAGS has greater than 95% indigenous content. During user trials in September 2020 the gun suffered a barrel burst injuring four personnel. The malfunction is expected to setback the program with DRDO going back to the drawing board.

The Advanced Towed Artillery Gun System (ATAGS) project was started in 2013 by DRDO to replace older guns in service in the Indian Army with a modern 155mm artillery gun. DRDO laboratory Armament Research and Development Establishment (ARDE) partnered with private players Bharat Forge Limited, Mahindra Defence Naval System, Tata Power Strategic Engineering Division and public sector unit Ordnance Factory Board (OFB) for this purpose.

The development of the gun took about 4 years and is expected to be complete by March 2017. The delay in completion of the project was attributed to realization of ordnance and recoil system and supply issue with manufacturing of sub-systems. The gun is expected to start user trials in 2017 and production is expected to start in 2019.

It was first publicly showcased at 68th Republic Day parade on 26 January 2017.

The gun consists of a barrel, breech mechanism, muzzle brake and recoil mechanism to fire 155 mm calibre ammunition with a firing range of 48 km. It has an all electric drive to ensure reliability and minimum maintenance over a long period of time. It has advanced features like high mobility, quick deployability, auxiliary power mode, advanced communication system, automatic command and control system with night capability in direct fire mode. The gun is two ton lighter than guns in the same category and is designed to provide better accuracy and range and is capable of firing five successive rounds in short duration. It is compatible with C3I systems like Artillery Combat Command and Control System (ACCCS) called Shakti for technical fire control, fire planning, deployment management, operational logistics management of the Indian Army.


Trials

DRDO conducted the proof firing of armament for the 155/52 calibre Advanced Towed Artillery Gun System on 14 July 2016. The test was successful.

Fully integrated, 155-millimeter artillery gun fired its first rounds of live ammunition at the Proof and Experimental Establishment (PXE) in Balasore, Odisha on 14 December 2016.

During trials in 2017, ATAGS broke the world record for 155 mm gun by firing the round to a distance of 47.2 kilometres. It again registered a maximum distance of 48.074 kilometres with high explosive–base bleed (HE–BB) ammunition, surpassing the maximum ranges fired by any artillery gun system in this category.

The gun successfully completed trials and the manufacturing of first lot of 40 guns is to start soon.

The gun underwent user trials in September 2020 and suffered a major setback with a barrel burst.

Users

Indian Army - In August 2018, Defence Acquisition Council approved the procurement of 150 ATAGS with an estimated cost of ₹3,364.78 crore (US$470 million).

The K9 Thunder is a South Korean self-propelled 155 mm howitzer designed and developed by the Agency for Defense Development and Samsung Aerospace Industries for the Republic of Korea Armed Forces , and is now manufactured by Hanwha Defense . K9 howitzers operate in groups with the K10 automatic ammunition resupply vehicle variant. The entire K9 fleet operated by the ROK Armed Forces is now undergoing upgrades to K9A1 standard, and a further development of a K9A2 variant is in process. The K9 Thunder saw its first combat during the bombardment of Yeonpyeong on 23 November 2010. Six ROKMC howitzers engaged against the surprise attack from the North Korean artillery . Prior to the battle, the howitzers returned from a scheduled firing exercise, using most of the shells stored within the howitzer. In addition, one howitzer experienced a problem during the exercise when a shell became stuck in the barrel, disabling it. Two units received slight damage to their firing control systems d

Haubits FH77 | Artillery Gun | Indian Army | Indian Artillery Core | Indian Defence Forces

Haubits 77 (Swedish "Field Howitzer 77") or FH77 is a Swedish 155 mm howitzer. It was developed and manufactured by Bofors . It was available in two versions, the original (sometimes referred to as Haubits 77 A) with a sliding block mechanism, and the later FH77 B export version with an interrupted screw breech. India is currently developing an upgraded (155mm/45 calibre) version of the FH-77 called FH-77 B02. Design and Development In the 1960s Sweden started to look for a replacement for the French Haubits F (Obusier de 155 mm Modèle 50). The American M109 howitzer was offered and tested. Though the price was low the Swedish Arms Administration found the high maintenance costs, the low rate of fire and the not so good mobility of the M109 made it worth the effort to develop a domestic howitzer. The FH77 was the first field howitzer featuring an APU to make it self-propelled for tactical movement. The rate of fire was, at the time, exceptionally high for a 155 mm howitz

The 122-mm howitzer D-30 (GRAU index 2A18) is a Soviet howitzer that first entered service in 1960. It is a robust piece that focuses on the essential features of a towed field gun suitable for all conditions. The D-30 has a maximum range of 15.4 kilometers, or over 21 km using RAP ammunition. With its striking three-leg mounting, the D-30 can be rapidly traversed through 360 degrees. Although no longer manufactured in the nations of the former Soviet Union, the D-30 is still manufactured internationally and is in service in more than 60 countries' armed forces . The barrel assembly of the 2A18 gun is used by the 2S1 self-propelled howitzer. There are also Egyptian, Chinese, Serbian and Syrian self-propelled variants and conversions. The Syrian conversion utilizes the hull of a T-34 tank. The 122 mm (originally 48 lines) calibre was adopted by Russia in the early 20th century, becoming very important to Soviet artillery during the Second World War. Development of the D-30 began
