'The radar lock': What happens when USS Spruance spots danger near USS Abraham Lincoln
The USS Spruance uses its Aegis AN/SPY-1 radar to detect, lock, and destroy incoming threats from a 50-mile defensive patrol distance, shielding USS Abraham Lincoln and its 5,680-crew from hostile swarm attacks at sea.
Shielding 5,680-Crew Carrier
The USS Spruance serves as the primary defensive shield for the USS Abraham Lincoln. Operating within a strict 50-mile defensive patrol distance, the destroyer creates a safety ring around the aircraft carrier, intercepting incoming drones and ballistic missiles in hostile maritime zones.
Scanning 360-Degree Combat Zones
The destroyer uses the advanced Aegis Combat System and its AN/SPY-1 radar to continuously scan the horizon. Providing complete 360-degree coverage, this powerful radar is sensitive enough to detect threats as small as a golf ball from hundreds of kilometres away, clearly distinguishing between friendly aircraft and hostile projectiles.
10-Second System Reaction
Once a hostile object is detected, the radar system establishes a firm lock and instantly calculates the exact speed, altitude, and trajectory. The advanced computers feed this engagement data to the weapons systems, enabling a rapid 10-second system reaction time to neutralise sudden aerial threats before they approach the carrier.
Firing Mach 3 Interceptors
From its 96-cell Vertical Launching System (VLS), the warship launches Standard Missile-2 (SM-2) or SM-6 interceptors to eliminate the aerial threat. These defence missiles travel at speeds exceeding Mach 3, intercepting the hostile target mid-air long before The Aegis radar system allows the USS Spruance to track and engage hundreds of targets simultaneously, rather than just 100. This immense multi-target processing capability is crucial when facing coordinated drone and missile swarm attacks designed to overwhelm naval defences.it can reach the carrier group.

Deck Gun and Close-In Defence
If a missile breaches the outer defence layers, the destroyer employs a layered close-in defence including its 5-inch/62-calibre deck gun, the ODIN laser system, and its 20mm Phalanx Close-In Weapon System (CIWS). While the deck gun and laser engage incoming threats, the automated Phalanx cannon acts as the last line of defence, firing up to 4,500 tungsten armour-piercing rounds per minute to shatter any remaining targets.
90 Combat Aircraft Protected
By eliminating threats several kilometres away, the USS Spruance ensures the 100,000-tonne aircraft carrier continues its operations uninterrupted. The USS Abraham Lincoln and its embarked air wing of up to 90 fixed-wing and rotary combat aircraft remain fully capable of executing their global strike missions.
