Background

Overview

Understanding the evolving nature of warfare is crucial for India's national security, defence planning, and military modernization efforts. It informs strategic decisions on procurement, doctrine, and force restructuring to effectively counter contemporary threats, especially from adversaries with significant military capacity and strategic depth.

Modern conflicts demonstrate that air superiority alone is insufficient to guarantee victory, with networked air defence systems and cost-effective drone technologies challenging traditional air power doctrines. This necessitates a re-evaluation of defence strategies to incorporate integrated air defence and joint operations.

Facts & tables

Key facts

Air superiority alone is no longer sufficient to win a war

Recent conflicts in Ukraine and Iran illustrate that even with air dominance, decisive outcomes are not guaranteed.

Networked air defence systems can deny airspace control

Ukraine's networked air defence kept a larger air force at bay, highlighting its critical role in contested low-level airspace.

Cost-arithmetic favours cheaper drones against expensive interceptors

Shahed-type drones (costing $20,000-$50,000) force the use of interceptors costing millions, creating an unsustainable cost burden for the stronger force.

Forces a global doctrinal rethink in modern air forces

These limitations are compelling air forces worldwide to reconsider their operational doctrines and integrate diverse defence capabilities.
