I found this to help myself understand the term caliber in artillery.

Caliber (artillery) - Wikipedia, the free encyclopedia
In artillery, caliber or calibre[nb 1] is the internal diameter of a gun barrel, or by extension a relative measure of the length.

The length of the barrel (especially for larger guns) is often quoted in calibers. The effective length of the barrel (from breech to muzzle) is divided by the barrel diameter to give a value. As an example, the main guns of the Iowa-class battleships can be referred to as 16"/50 caliber. They are 16 inches in diameter and the barrel is 800 inches long (16 × 50 = 800). This is also sometimes indicated using the prefix L/; so for example, the most common gun for the Panzer V tank is described as a "75 mm L/70," meaning a barrel with an internal bore of 75 mm, and 5,250 mm long (17 ft 2.69 in).

The bore to barrel length ratio is called caliber in naval gunnery, but is called length in army artillery. Before World War II, the US Navy used 5"/51 caliber (5"/L51) as surface-to-surface guns and 5"/25 caliber (5"/L25) as surface to air guns. By the end of World War II, the dual purpose 5"/38 caliber (5"/L38) was standard naval armament against surface and air targets. All three had a bore diameter of 5 inches (not 5.51 or 5.25 or 5.38 as often misread).

once we make that gun we should go for this



so that it can be easily transported by air and quickly deployed in border.

Regarding tracked & Wheel:





Rebirth of BHIM self-propelled howitzer

DRDO is all set to dust off and review BHIM self-propelled howitzer Project once again,After 11 years been in storage, due to ban imposed on Denel company which was accused of paying bribes and it's SPH was dropped from consideration.DRDO had successfully had integrated 155-mm / L52 howitzer T6 turret, developed by Denel of South Africa with Indian made Arjun tank chassis . After corruption controversy which came to lime light in 2005, DRDO again send Request for proposal (RFP) in 2007 .but only Samsung Techwin responded to the proposal with their K-9 gun.Project was left with single vendor proposal, hence another RPF was re-issued after considerable break to make sure that RPF attracts more proposal and it has been rumoured that SWS Bofors, Nextel, Samsung Techwin along with Soltham have responded to RPF issued by DRDO for the replacement gun

In 1999-2000 Indian army had conducted successful trails of the gun with Arjun chassis and Denel also had successfully demonstrated their own T-72 based howitzer in India for Indian army.Indian army had requirement of 400 mounted 155-mm / L52 howitzer, out of which 200 could be based on Arjun chassis and another 200 to be mounted on modified TATRA trucks. Decision on selection of the gun will take place this year.

Recent Picture of OFB updated 155mm of 45cal Gun..



I think it is Ext ream Important to go ahead with this barrel with the pending projects, When the 52cal barrel will be selected after years of testing and selection we will have some 45cal SPGH operational, Once the 52cal gun selected MOD can switch newer batch of SPGH with 52cal barrel..

we have made armor cabin for A3 same type of thing can be made for the howitzer

From my Personal collection:








We already making MPV and Armored vehicle and this example with Stallion why not a TATRA..

How come the G7 features an additional range, and how usefull is it ?
G7 105mm barrel is of 52cal also the BB and Rocket assisted charge helps it reaching that many KMs..

The advantage is its light gun with very long range good against fast deployment of troops or over mountain ranges..

sir, will it protect from the counter air bust artillery fire from enemy ??
bullet is one thing but high velocity pallets is another matter.
It saves from both bullet and arty fragments..

But a direct hit above cannot save, the fragments wont do much damage but the shock wave..

That my dear is the trade secret and genius of Dr Gerald Bull,However the range quoted is one with extended range base bleed projectiles!

100 made-in-India Bofors artillery guns



NEW DELHI: Defeating the ghost of Bofors scandal that has haunted successive Congress governments, the Indian Ordinance Factory Board (OFB) has set on a daunting task of manufacturing 100 Bofors artillery guns indigenously from scratch, nearly 24 years after the first of these Swedish guns were inducted into the Indian Army.
The Indian Army has already placed an order with the OFB and the effort if successful will save the country millions and would give the country a capability to further improvise the guns to add punch to its firepower.
Speaking exclusively to Express, Minister of State for Defence M M Pallam Raju said: "The Indian Army has put a substantial order for 100 of these Bofors guns. It is a huge task for the OFB. If we are successful, it will be a huge technology boost to the Indian defence market."
The designs are already with the OFB and the Indian Army's decision to go for 100 guns at the beginning of the project and testing the guns simultaneously as the manufacturing goes on, will cut down the time of fructification of the project.
Earlier, the Army contemplated first getting the two prototypes of the guns, then putting them to extensive field trials. Once the designs were validated, the guns were to be mass produced.
Seeing the delays in previous projects, the defence ministry has decided to set up a Monitoring Committee to oversee the progress of the project and involve the Army in the project from the beginning.

Army Places Orders For 100 Howitzers with OFB


With several failed attempts to procure howitzers from foreign sources on its back, the Indian Army has placed orders for 100 artillery guns with the Ordnance Factory Board (OFB).

The Army has issued several tenders for procuring different types of howitzers in the last two decades but has failed to do so due to some problem or the other.

"The Army has placed orders with the OFB for procuring one hundred 155mm 52 calibre howitzers and this will be developed on the basis of Transfer of Technology (ToT) done by Bofors," Minister of State for Defence M M Pallam Raju said here

He said indigenous development of the howitzers would continue alongside trials by the OFB and within a specific time frame, the guns would be delivered to the Army.

The Minister said this indigenous development programme was not likely to have any impact on procurement of several types of gun systems such as 145 Ultra Light Howitzers, 180 Self-Propelled Howitzers and 400 Towed Howitzers through global tenders.

The OFB has been producing major components of the gun, such as barrel, breach mechanism, muzzle break, loading trough, recoil system along with the elevating and traversing cylinders, and supplying these to the army as spares.

As part of its over Rs 20,000 crore artillery modernisation plan, the Army is looking at inducting several types of howitzers through inter-governmental pacts and global tenders.

Army Chief Gen V K Singh had promised last year that at least one type of artillery gun would be inducted into the Service in 2011-12 but it is still waiting for it.

The Bofors 155mm howitzers were the focus of a kickback scandal targeting former Prime Minister Rajiv Gandhi in the late 1980s, but the artillery gun performed remarkably in the Kargil war.

I guess accuracy would be compromised, anyways how accurate are the howitzers ?

My thinking may be out of date, and I never served in artillery, but howitzers have to adjust fire based on observation by forward observers in any case. The accuracy depends on the observers.
