New Delhi: The Indian Navy has officially issued a Request for Information (RFI) to global defence manufacturers for the acquisition of long-range submarine-launched land-attack cruise missiles (LACMs), a move set to significantly enhance its undersea precision strike capabilities.
This RFI marks an important step in modernising India’s conventional submarine fleet with deep-strike options against land targets beyond the littoral zone.
The RFI outlines clear technical benchmarks: a minimum strike range of 50 km, extending beyond 500 km, and a weight limit of 1,500 kg (including launch capsule), compatible with 533 mm torpedo tubes on existing submarines.
Details of Submarine-Launched Land-Attack Missiles India
The Indian Navy has traditionally relied on submarine-launched anti-ship missiles and strategic ballistic missiles for coastal defence and deterrence roles. However, conventional submarines have not possessed a true submarine-launched land-attack capability with extended range and precision—a gap this RFI seeks to fill.
With regional security dynamics rapidly evolving in the Indian Ocean Region, the Navy’s demand for long-range LACMs reflects a strategic priority to extend precision strike reach inland and beyond coastal territories without exposing submarines to surface threats.
Key Specifications of the Submarine-Launched Land-Attack Missiles India
The RFI document specifies several technical and operational requirements:
Range & Performance
- Submarine-Launched Land-Attack Missiles India Range: 50 km to over 500 km, providing standoff target engagement.
- Operational accuracy with high survivability in complex environments.
Weight & Compatibility
- Maximum launch system weight: < 1,500 kg, including launch capsule.
- Designed for standard 533 mm torpedo tube launch on India’s current conventional submarine fleet.
Environmental and Operational Robustness
- Must withstand hostile maritime conditions including electronic warfare.
- Capable of launch at periscope depth (15–100 m) and compatible with submarine motion tolerances.
Mission Reliability
- High reliability standards expected across navigation, guidance systems, and warhead effectiveness.
These specifications ensure the missile system will deliver effective long-range precision strikes from submerged platforms with minimal compromise on stealth and survivability.
Implications of Submarine-Launched Land-Attack Missiles India
The acquisition of submarine-launched land-attack missiles is expected to:
- Expand the Navy’s conventional deterrence options.
- Provide deep-strike capability against high-value land targets without surfacing.
- Enhance stealth and operational flexibility for patrol submarines.
This development also comes amid broader efforts to modernise undersea warfare capabilities and align them with India’s evolving maritime strategy in the Indo-Pacific.
Global and Regional Comparison
While India seeks to equip its conventional submarines with long-range land-attack missiles, neighbouring countries have taken steps in similar directions:
- Pakistan has tested submarine-launched cruise missiles such as Babur-3 with a claimed range of about 450 km.
- China conducts submarine cruise missile operations, primarily anti-ship in focus, though with growing capabilities.
In this context, the Indian Navy’s RFI signals intent to match or exceed regional undersea strike standards.
What Comes Next in the Procurement Cycle
An RFI is typically the initial phase of acquisition. If feasible responses are received, this would lead to:
- Acceptance of Necessity (AoN) by the Defence Ministry.
- Competitive Request for Proposal (RFP) issuance.
- Formal bids and eventual procurement contracts.
This phased acquisition process ensures that any future missile system selected meets the Navy’s technical, operational, and long-term sustainment needs.
