The changing character of warfare and recent wars indicate a change in the trend related to the duration of wars. The conflicts are continuing for longer periods but with a wavering tempo of operations. The changing trend has reopened the debate about the aspect of readiness for a short and intense war or a long protracted one. The level of preparation required by the defence forces is determined by the combination of the expected duration of the war and the likely tempo/intensity of operations. Several key factors contribute to air war endurance and affect the duration, effectiveness, and efficiency of air campaigns. There is a need to review the factors associated with the use of air power vis-à-vis air war endurance. Air powers in prolonged conflicts must demonstrate resilience, adaptability, and effective resource management to endure the challenges associated with extended durations of war and contribute to achieving the desired strategic objectives over the long term. The Indian airpower, mainly IAF should be ready for short and intense war and be prepared for long-drawn standoff.
