HMS Queen Elizabeth: Analyzing the Defense Capabilities Beyond Aircraft
The HMS Queen Elizabeth, a cornerstone of the United Kingdom’s naval power, represents the cutting edge of aircraft carrier technology. As the lead ship of the Queen Elizabeth class, her primary strength lies in her ability to launch and recover a formidable array of F-35B Lightning II stealth fighters, making her a powerful force projection platform. However, when evaluating her defensive capabilities outside of her air wing, questions arise about her ability to independently defend herself against modern threats.
Designed for Carrier Strike Operations
HMS Queen Elizabeth was not designed as a standalone warship but as a part of a carrier strike group (CSG). This doctrine leverages a fleet of supporting vessels, including destroyers, frigates, and submarines, to provide layered protection against air, surface, and subsurface threats. As a result, her onboard defenses are tailored to complement this integrated approach.
Self-Defense Systems
Despite her reliance on a strike group, HMS Queen Elizabeth is not entirely defenseless. She possesses several self-defense systems, including:
Phalanx Close-In Weapon System (CIWS)
The ship is equipped with Phalanx CIWS, an automated radar-guided Gatling gun system capable of firing up to 4,500 rounds per minute. It is designed to intercept incoming missiles and aircraft at close range, acting as a last line of defense.
Limitations: While effective, CIWS is only suitable for short-range engagements and provides no protection against longer-range threats.
30mm Automated Small Caliber Guns
The ship features 30mm guns for defense against fast inshore attack craft (FIAC) and smaller surface threats. These guns are valuable in littoral environments but are not sufficient for engaging heavily armed or long-range adversaries.
Radar and Electronic Warfare (EW) Suites
HMS Queen Elizabeth’s advanced radar systems, including the Artisan 3D radar, provide excellent situational awareness. Coupled with electronic countermeasures, these systems can detect, track, and disrupt incoming threats.
Potential Vulnerabilities
While HMS Queen Elizabeth boasts cutting-edge technology, her defense suite may be considered lacking compared to the heavily armed carriers of some other nations, such as the U.S. Navy’s Nimitz or Ford-class carriers. Potential vulnerabilities include:
Lack of Vertical Launch Systems (VLS)
Unlike some U.S. and French carriers, HMS Queen Elizabeth does not feature a VLS for surface-to-air missiles (SAMs). This limits her ability to engage long-range aerial threats autonomously, relying instead on escorts like the Type 45 destroyers equipped with Sea Viper missiles.
Limited Anti-Submarine Warfare (ASW) Capabilities
Without onboard ASW weaponry, the carrier depends on Merlin helicopters and accompanying ships for subsurface threat detection and neutralization.
Susceptibility to Advanced Hypersonic Threats
Modern hypersonic missiles, which can evade conventional defensive systems, pose a significant challenge. HMS Queen Elizabeth’s existing CIWS and radar may struggle to counter such advanced weapons.
