    I've a different question. During mass testing, [say using random sampling technique], if one round or multiple rounds falter among few thousand, should it be cause for concern?
    The probability of that happening is quite low, isn't it?

    Actually no. The practices in vogue in OFB is such that QA is always a cause of concern. We have had more incidents of barrel burst out of QA issues in armament than poor metallurgy of equipment made.

    But certain percentage is taken as an acceptable failure rate (quite low, almost in decimals if am not wrong). And if it exceeds, the complete Lot is recalled as everything is as per Lot and serial numbers.

    Luckily and thankfully, the recall process is stringent.

    IMPLICATIONS FOR INDIA? K-9 HOWITZER MALFUNCTION KILLS TWO S KOREAN SOLDIERS
    TUESDAY, AUGUST 22, 2017 BY INDIANDEFENSE NEWS

    [​IMG]
    South Korea self-propelled Howitzer K-9 engages in a live-fire exercise
    The explosion of a self-propelled howitzer ‘K-9 Thunder’ that killed South Korean soldiers last week is appeared to have caused by the combustion of gunpowder that is used to propel artillery shells toward the target, local media reports.
    “For reasons unknown, there was smoke inside the howitzer’s breach block assembly,” the South Korean Army official was quoted as saying by The Korean Herald on Monday. “According to our on-site investigation, three sets of gunpowder were completely burned down without any trace,” source said.
    Two South Korean soldiers were killed and five injured in an explosion inside a K-9 Thunder during artillery training Friday in Choerwon, Gangwon Province.
    The Army decided to halt K-9 artillery firings for training purposes until the official investigation on the exact cause of the explosion is concluded. The training was designed to improve accuracy of counter-artillery attacks toward North Korea.
    Touted as “high-quality indigenous artillery” for its longer range and higher rate of firing, he indigenous howitzer is manufactured by Samsung Techwin and has been exported to four foreign countries including Turkey, Poland, Finland and India.
    However, since malfunctioning of two howitzers in 2010 during Pyongyang’s 2010 bombardment of Yeonpyong Island, the howitzer has been under scrutiny.
    More than 1,000 K-9s have been produced and they suffered from 1,700 malfunctions over the past five years. It means that every K-9 suffers from about two cases of malfunction every five years. This is similar to a car driven for five years, one might see a similar number of malfunctions.
    It is worthy to note that, Larsen & Toubro (L&T) had signed a contract with Hanwha Techwin (HTW) in for execution of the 155mm/52 Cal tracked self-propelled (SP) gun program for the Indian Army.
    L&T was declared as the sole qualified bidder, post User Evaluation Trials, based on the performance of the K-9 Vajra-T, a self-propelled howitzer appropriately customised and fielded by L&T with HTW as the technology partner. The K9 Vajra-T gun is an enhanced version of HTW’s K9 Thunder, to suit specific requirements of the Indian Army including desert operations.

    BAE to join hands with ordnance factories to make high range artillery guns


    Nagpur: After supplying the M777 ultralight howitzers to the Indian Army, multinational weapons maker BAE Systems will now be tying up with the Ordnance Factory Board (OFB) to make 155x52mm artillery guns. The OFB, which has already developed the Indian 155x45mm guns based on the Bofors howitzers, will make a superior version with BAE.

    The first batch of the M777 guns was recently delivered to the Army from the US. Due to its light weight, it can be shifted easily and even transported by helicopter. Now BAE, OFB, and Bharat Earth Movers Limited (BEML) plan to together make the 155x52 calibre of guns.

    The OFB has at present made Dhanush — the indigenous 155x45 mm howitzer with a higher range than the original Bofors. The new gun being planned to be made along with BAE Systems will have a superior range than even Dhanush, on account of the higher calibre.

    A mounted gun, it will have faster mobility as against a conventional towed howitzer. The guns will be mounted on a Tatra vehicle. It is planned to make the prototype by March next year with user trials expected to being in a couple of years, say sources.

    A memorandum of understanding will be signed between OFB, BAE Systems and BEML on Tuesday at Kolkata. The guns would be made at the Gun Carriage Factory (GCF), Jabalpur, where the Dhanush is also being manufactured.


    The MoU will entail a knowledge sharing agreement. BAE will share know how with OFB. BEML will be providing the vehicle on which the gun will be mounted. The three will be working in tandem on the project, said sources.


    Meanwhile, the OFB's Dhanush project has been facing several hiccups. Last month, CBI registered a case after one of the gun's spare parts, supplied by a private vendor from a Chinese manufacturer, was passed off as a made in Germany product. The agency has registered FIR against Sidh Sales, the Delhi-based private company and unknown officials of the OFB.

    At the same time, a case of barrel burst was reported in Korean K9 Thunder guns, for which India has signed a deal. Two soldiers were killed in the incident.

    these bearings r not critical technologies, Chinese reverse engineer them from Germany bearings, India has one of the best world class automobile bearing manufacturing companies, they r capable of manufacturing these, it's strange Chinese duplicates can seek into our guns too, this is fishy.

    maybe OFB manufactured ammo is all faulty & they r not upto the mark, one reason for barrel burst, or OFB has poor metallurgy experts, I would bet the gun would have been designed better if it was done in the southern part of India, Bengal has bad reputation for industry standards.

    it is now openly known that there was problem was with shell and not the gun in shell hitting the muzzle break. I had posted this very thing when this news came out. I also posted why it happens. The gun is perfectly fine and we must induct it asap.

    I wonder how much more tests would it take, it's no brainer to make a weapon which is multi purpose which can be used in all weather & all kinds of geography, we should concentrate on weapons for specific areas, light artillery for mountains, heavy artillery for core corps facing Pakistan, I don't understand why our army wants rail guns weighing like a feather, there is some lobbying going on by agents, hope these OFB guys rectify their mistakes & make a better gun.

    World-record 'gun salute' to incoming defence minister Nirmala Sitharaman
    Range, accuracy and consistency are the key attributes of an artillery gun


    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: ammunitionhandling, 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).
