    World-record 'gun salute' to incoming defence minister Nirmala Sitharaman
    [​IMG]
    Defence Minister Nirmala Sitharaman


    On Monday, in trial firing at the Pokhran Ranges in Rajasthan, the advanced towed artillery gun system (ATAGS) being indigenously developed for the Indian Army demonstrated its potential to be a world-beating system.

    The 155-millimetre, 52-calibre gun-howitzer fired three shells out to a world-record distance of 47.2 kilometres from the gun position. This was achieved using special, long-range ammunition called “high explosive – base bleed” (HE – BB). In comparison, 155-millimetre, 52-calibre guns in service worldwide fire this ammunition to maximum ranges of 40-45 kilometres.

    The achievement coincides with the appointment of Nirmala Sitharaman as defence minister.

    The ATAGS is being developed by the Defence Research & Defence Organisation (DRDO) on two parallel tracks – one prototype in partnership with Tata Power (Strategic Engineering Division) and another with Bharat Forge. The prototype that broke the record was the Tata Power (SED) gun.

    Earlier, on Saturday, the same gun had broken another record by firing “high explosive – boat tail” (HE – BT) ammunition to a range of 37.2 kilometres.

    Range, accuracy and consistency are the key attributes of an artillery gun. A longer range allows more area to be engaged from a “gun position”, without having to redeploy (or shift) the guns.

    The secret of the ATAGS longer range is its larger chamber – 25 litres, compared to 23 litres in most 155-millimetre guns like the French Nexter and Israeli Elbit guns the military has evaluated. A larger chamber packs in more high explosive propellant, which shoots out the warhead further.

    The need to cater for this higher “shock of firing” makes the ATAGS a heavier gun. It weighs in at 17-18 tonnes, while comparable guns worldwide weigh 14-15 tonnes.

    So promising is the ATAGS that both existing prototypes were paraded on January 26 in New Delhi.

    After the gun successfully completes development and firing trials, the army is likely to procure at least 2,000 ATAGS. At an estimated Rs 15 crore apiece, that will result in Rs 30,000 crore in business for the production eco-system, benefiting a large number of private defence firms.

    With the current round of “summer trials” having successfully concluded in Pokhran, the ATAGS will now undergo modifications and prepare for “winter trials” in December, probably in Sikkim. Each vendor will build three more ATAGs gun prototypes to expedite trials.

    The first ATAGS firing trials were carried out in Balasore, Odisha, last December.

    While ATAGS looks much like the Bofors FH-77B — the infamous “Bofors gun” that India bought 410 of in the 1980s before scandal derailed indigenous construction — the ATAGS is in face significantly bigger than the 155-millimetre, 39-calibre Bofors.

    When talking about a 155-millimetre, 52-calibre gun, the first figure denotes the “bore” of the gun, or the width of the gun barrel; while calibre relates to barrel length. The higher the calibre, the longer the barrel and, therefore, the greater its range. A third parameter is chamber size, which determines how large a projectile can be fired from the gun, and therefore how much damage a round can inflict on the target.

    Another global first in the ATAGS is its all-electric drive, which supersedes the more unreliable hydraulic drives in other towed guns. The all-electric drive operates all the ATAGS’ gun controls: ammunition handling, opening and closing the breech, and ramming the round into the chamber.

    The ATAGS is the world’s only gun with a six-round “automated magazine” that fires a six-round burst in just 30 seconds. Most other existing 155-millimetre, 52-calibre guns have three-round magazines, which must be reloaded after firing three rounds.

    A high “burst fire” capability will provide the army a significant advantage since artillery causes most casualties in the initial burst of fire, when enemy soldiers are caught in the open (and not after they dive into their trenches).

    NOW MUZZLE HIT OCCURS IN M-777 HOWITZERS DURING TRIALS IN POKHRAN
    Tuesday, September 12, 2017
    by Indiandefense News

    by Shishir Arya

    Nagpur:
    A muzzle hit occurred in the M-777 ultralight howitzers procured from the US, during trials in the Pokhran desert last week. The first batch of the guns, made by BAE Systems, was delivered in May this year as a part of the deal to buy 145 pieces in all. M-777 is the first acquisition of high calibre howitzers after Bofors.
    A senior official in army's artillery wing confirmed the incident. It is a small incident and most probably due to faulty ammunition." A joint investigation is being carried out to ascertain the cause," the officer told TOI.

    The muzzle is fixed on the top of a barrel. If a shell dashes through it, the range is reduced considerably and the muzzle gets damaged too.
    A similar issue was seen in Dhanush, the Indian gun designed on the lines of the Swedish Bofors by the ordnance factory. The howitzer is being made at the Gun Carriage Factory (GCF), Jabalpur.
    During trials in July, there was muzzle hit in the Dhanush guns. Prior to this, there was an incident in May also. The preliminary report over the May incident in Dhanush had blamed the ammunition.
    Last month, there was as barrel burst in K-9 Thunder guns during trials in Korea. Guns of the same make are being acquired for India.
    On the K-9 guns, the army official said, "The incident took place outside India. As the Korean ammunition and loading systems were in use, the incident has to be taken independently."
    Top sources in the army say Dhanush is expected to be inducted within six months to a year. An investigation is being conducted and it is suspected that even in the Indian gun, faulty ammunition may be the cause.

    Repeated incidents of muzzle hit and one barrel burst in Dhanush has pushed back its final induction. Even in the original Bofors, nearly 40 cases of muzzle hit were reported. If final report for Dhanush blames the ammunition, doubts can be set aside on its design, said sources.
    Apart from making Dhanush, the Ordnance Factory Board (OFB) has also tied up with BAE Systems to make mounted howitzers of 155x52 mm calibre. It will be having a higher range than Dhanush due to length of the barrel. Bharat Earth Movers Limited will be making the vehicle on which the gun will be mounted.
    As the army has to replace the ageing Bofors guns, the weapons are being made by private as well as government entities. These include Dhanush by ordnance factories, K-9 Vajra by Larsen and Toubro in collaboration with Korean Hanwa Techwin, ATAGS of Bharat Forge-Tata Power SED, apart from M-777 of BAE Systems.

    Gun That Created A New World Record

    The 155x52 mm howitzer jointly developed by Bharat Forge and TATA Power SED has created a new world record by achieving a range of more than 48 km. The trials were held last week. This surpasses all the previous records for any 155mm artillery in the world, said a statement issued by development partners of the gun. The project was started in 2014.
    The guns are being made by Bharat Forge, a Kalyani Group Company and TATA Power SED as development partners of Armament Development Research Establishment (ARDE), Pune. The over 48 km range was achieved with the basebleed version of the ammunition.

    Its time we should out source all critical ammunition production to the private sector, so that proper procedure, quality and output is adhered to by private companies. These private companies will be accountable for their product quality and production output. Additional penalties cab be levied on these firms for failing to meet the prescribed production parameters.

    I was saying it for long the production quality of ammo was pathetic

    M777 incident is a boon for our indegenous guns

    This a slap on the face of the people who are considering Dhanush howtizer as a failed projects

    Private sector takes DRDO programme on high trajectory

    Bharat Forge, Tata Power SED speed up DRDO’s towed gun programme

    MUMBAI, SEPTEMBER 11:

    Engaging the private sector has yielded rich dividends for State-owned Defence Research and Development Organisation (DRDO), which is developing the high-capacity Advanced Towed Artillery Gun System (ATAGS).

    Valued at $4.5 billion, the production order for the guns, which are currently undergoing intensive field trials, could be a potential windfall for the two private defence companies engaged in the project.

    As the Army seeks to fill its requirement of over 1,500 towed guns, the ATAGS is being developed in a joint project with two private defence firms, Tata Power SED and Bharat Forge.

    Sources said that while Bharat Forge, a Kalyani Group company, has “developed and provided diverse inputs in design, manufacture and development”, Tata Power SED ( Strategic Engineering Division) has provided the automotive system, understructure assembly automation, breech system, recoil system and fixed firing stand.

    The segments provided by Tata Power SED account for approximately 70 per cent of the gun system, the sources said.

    Immense accuracy
    The firing of the gun, and “its immense accuracy”, has turned out to be a fitting example of how the DRDO and the Ordnance Factory Board, along with the private sector, can compete with global defence giants, said DRDO sources.

    In a test round earlier this week, the gun fired a round at 48 km, as compared to 40-45 km at Pokhran, revealing “the scale, depth and accuracy of its range”. Comparably, 155 mm, 52-calibre guns can fire their ammunition to 40-45 km, the sources added. Senior officials of the DRDO and Armament Research and Development Establishment were present at the trial.

    Typically, only State-owned companies are given such orders. Roping in the private sector is seen to have helped the production of the ATAGS. “The system incorporates futuristic technologies and is slated to have an all-electric drive for ammunition handling, breach opening and closing, which will provide huge reliability,” the sources pointed out.

    Two prototypes were developed and tested in Odisha last December, they said, adding that the 25-litre chamber volume of the ATAGS allows for “higher propellant charge to fire ammunition at longer range in comparison to contemporary artillery”. Its autoloader also has a six-round magazine, which facilitates rapid fire of ammunition, they said, adding that it is another remarkable feature of the ATAGS.

    The Army needs over 1,500 155 mm, 52-calibre towed howitzer and 800 mounted gun systems of the same calibre. The sources confirmed that the next stage of trials with further modifications will be in December.

    The barrel of one of the M-777 Guns being acquired from the US exploded yesterday during its trialat Pokharan Field Firing Ranges in Thar dessert in Rajasthan.

    During the firing on 02 Sep 17, the projectile which was fifth of the series; exited the barrel in multiple pieces, causing thus the accident, sources in the army said citing initial reports.

    The US manufactured gun was firing Indian ammunition, they said.

    There was no report of any injuries at the spot following the mishap.

    The field firing was being conducted for compilation of firing tables.

    “The barrel of the gun has been damaged, extent of which is being assessed by Joint Investigation Team, ” said the sources.

    The Joint Investigation Team is on the Site.
    The firing has been suspended till the investigation is completed by the Joint Investigation Team.
    The Army had received the delivery of two M777 Ultra-Light Howitzers (ULH) and the trails were being carried out to prepare them for induction.

    These were the first new units of artillery to join the Army after a gap of three decades. India last inducted the Swedish Bofors guns in the 1980s, the deal of which kicked up a major controversy and stalled the Army’s artillery modernisation programme. However, the Bofors guns won the Kargil conflict for India and continues to be the Army’s mainstay.

    The M777 is a 155mm, 39 caliber towed artillery gun made of titanium and aluminium alloys and weighs four tonnes, enabling it to be transported under slung by helicopters.

    In November 2016, India signed the Letter of Acceptance (LoA) with the U.S. government under the Foreign Military Sales (FMS) programme for 145 BAE Systems-built M777A2 artillery guns in a deal worth $737 million.

    Looks like the problem is in shell, similar accident have happened with dhanush several times

    Did I not tell you all about this long back. PSUs not only make poor weapons but their products can be fatal also.

    Is there no quality check in ordnance factories? Why don't we privatise shell manufacturing under Govt. supervision. Wonder how they get ISO 9001:2000 certification!!!

    Muzzle hit and barrel burst are different things both can happen in all Artillery units.

    M777 has killed approx 14 people through malfunction over the years still that doesn't mean its an ineffective gun, from Ammo to Gun metallurgy to wrong operation could have been factors also it could be just seer bad luck. Lets not Jump the gun, lets wait what the final report says.
