New Non-Nuclear Agni-5 Variant with Bunker Buster Warhead to Fill IAF's Strategic Bomber Needs for Deep-Strike


India's Defence Research and Development Organisation (DRDO) is reportedly developing a new, conventionally-armed variant of the Agni-5 ballistic missile.

This strategic project is intended to provide the Indian Air Force (IAF) with a powerful deep-strike weapon capable of destroying heavily fortified and underground targets, addressing a significant gap in the nation's military capabilities.

The primary motivation for this new missile is the IAF's long-standing need for a weapon that can perform the role of a strategic bomber.

Currently, India does not operate heavy bombers like the American B-2 Spirit or B-52 Stratofortress, which are designed to carry massive ordnance over long distances.

For instance, the US employs the 13.6-tonne GBU-57 Massive Ordnance Penetrator (MOP), a bomb capable of penetrating up to 60 meters of reinforced concrete.

While the IAF's fleet of Su-30MKI and Rafale fighter jets are highly versatile, they lack the capacity to deliver such exceptionally heavy munitions deep into contested enemy airspace. The development of a conventional Agni-5 aims to provide a credible alternative.

To achieve this, the new missile variant will be equipped with an exceptionally large conventional warhead, estimated to weigh between 7.5 and 8 tonnes.

This substantial increase in payload reduces the missile's range from its nuclear-capable version's reach of over 5,000 km to a more tactical range of approximately 2,500 km.

A key feature of this new variant is its advanced design to overcome enemy Ballistic Missile Defence (BMD) systems.

This capability builds on technologies tested during "Mission Divyastra" in March 2024, which successfully demonstrated MIRV (Multiple Independently Targetable Re-entry Vehicle) technology for the Agni-5 platform.

The missile is being designed with two distinct warhead configurations to engage different types of targets.

The first is a bunker buster variant, engineered to penetrate 80 to 100 meters underground before detonation. It is intended for destroying high-value subterranean targets such as command and control bunkers, missile silos, and fortified nuclear storage facilities.

Its effectiveness relies on pinpoint accuracy, achieved through a sophisticated guidance system that uses ring laser gyroscopes and signals from both GPS and India’s indigenous NavIC navigation satellite constellation. This results in a reported Circular Error Probable (CEP) of less than 10 meters, making it highly precise.

The second configuration is an airburst warhead, designed to detonate at a specific altitude above a target area. This creates a massive shockwave and disperses fragments at high velocity, maximizing damage over a wide surface area.

A single missile with this warhead could potentially neutralize an entire enemy airbase, destroying runways, parked aircraft, radar installations, and support infrastructure in one strike. This would give the IAF a powerful tool for achieving air superiority early in a conflict.

The Agni-5 platform itself provides significant operational flexibility. It is a three-stage, solid-fuel missile that is canister-launched from a road-mobile transporter vehicle. This system allows for rapid deployment and makes the missile difficult for an adversary to locate and target before launch.

By adapting this proven intercontinental ballistic missile (ICBM) for a conventional role, the DRDO is creating a transformative strategic asset. This development will enable the IAF to hold critical, heavily defended enemy infrastructure at risk, providing a potent long-range strike option that compensates for the absence of a dedicated strategic bomber fleet.
 
It's unlikely to serve the same purpose as GBU-57 for the simple reason of accuracy. The GBU-57 hit a target the size of a small table; we will not achieve anything similar with a ballistic missile. It could be at best 10-20 meters, meaning this Agni-5 variant, besides the airburst variant, will serve some other purpose.
 
But how will IAF fire this missile? I mean, from which platform? It will be such a heavy munition. For that, we need bombers. India should make large bombers from the Ghatak platform, or either purchase Tu bombers from Russia.
 
This makes sense because there are a lot of underground bases which they can use as a major command centre, nuclear warhead storage, critical weapons and ammunition storage, major war bunkers, missile silos and critical communication network facilities.

We have already developed the missile so we can easily develop the large warhead with a chemical composition that makes the explosive very powerful. Before it enters service they will need to test the missile and warhead out properly in real world live conditions, how deep can the missile penetrate the earth, when it explodes, what happens when it blows up and the type and amount of damage that it can do.
 
In this scenario, Agni-5 will be used with multiple warheads, I guess. So, when it is launched against an airbase, there will be a devastating effect. The same thing goes for a military base, a naval base, or a port. A single missile [covers] 2-3 sq. kilometers, close.
 
Make it train launched so then it's has the speed , reach and rapid deployment capabilities like a bomber .
That would mean having a high-speed train which India is just venturing into!
Tracks are the stumbling-blocks for wheeled/maglev high-speed trains. Imagine hitting cattle at 431 km/h.
Most of our tracks have scant protection from wandering wildlife/cattle.
 
The Agni-5 in its airburst or bunker-buster versions are positively the way to go as the plan to acquire Tu-160M bombers has been nixed.
The only issue that detracts from comparing it to the Tu, is the missile's range.

The Agni-5 which has a warhead (for the planned modifications) that weighs close to 8 tonnes would only have a range of 2,500 kms.. This will mean that the bunker-buster/air-burst versions of the modified Agni-5 will only be able to reach mid-land China.

We need to think about how we can target the east coast of China with such a type of missile. An Agni-6 (!!!) with ability to use the conventional warheads as presently planned?

All happens on train tracks , but such trains run with escorts and are armoured, see James Bond movie, Golden eye . The Russians , Chinese and North Korea , all have them in reality . So copy them .

These ideas are out of movies but they are representing real armoured missile system carrying trains .
