Advanced Gun System (AGS)

Advanced Gun System (AGS)

To achieve an increased rate of fire and improved lethality while reducing operational crew headcount, the Zumwalt-class destroyer will employ the Advanced Gun System (AGS). A battery of two 155mm AGSs, firing-rocket assisted Long-Range Land Attack Projectiles (LRLAP) will provide precision strikes and volume fire at a range of up to 83 nautical miles. This system is equivalent to twelve 155mm howitzers and will see a three fold improvement in naval surface fire coverage when compared to current capabilities.

BAE Systems has the responsibility for the AGS. For more information visit BAE Systems website.

Autonomic Fire Suppression System (AFSS)

Autonomic Fire Suppression System (AFSS)

An advanced automated damage-control system combines sensors, cameras and automated firefighting capabilities to ensure that the Zumwalt has the fastest possible response time to life- and ship-threatening events. This system improves survivability in both peacetime and wartime while reducing the number of crewmembers needed for damage control.

Dual Band Radar (DBR)

Dual Band Radar (DBR)

The Zumwalt DBR integrates S-band and X-band radar capabilities in a single system. It delivers true multi function performance, simultaneously supporting self-defense/anti-air warfare, situational awareness, land attack, naval gunfire support, surface search, navigation and air traffic control. The DBR’s innovative software design allows automatic operation with minimal human intervention.

Integrated Composite Deckhouse & Apertures (IDHA)

Integrated Composite Deckhouse & Apertures (IDHA)

Constructed of rugged, lightweight composites, the angular deckhouse increases stealth by minimizing radar reflectance. The surfaces of the Zumwalt’s deckhouse incorporate all radar apertures and communication antennas, eliminating high-profile masts and rotating antennas.

Integrated Power System (IPS)

Integrated Power System (IPS)

The Zumwalt Destroyer is often called an all-electric ship. The efficient, quiet and economical design of the IPS generates all the energy needed for propulsion, electronics, combat, environmental and other ship systems.

Integrated Undersea Warfare (IUSW)

Integrated Undersea Warfare (IUSW)

The IUSW incorporates two types of sonar arrays in one automated system. The high frequency sonar provides in-stride mine avoidance capabilities, while the medium frequency sonar optimizes anti-submarine and torpedo defense operations. The use of sophisticated target algorithms better enables the Zumwalt Destroyer to engage enemy submarines and, at the same time, minimize crew headcount requirements.

MK57 Vertical Launching System (VLS)

MK57 Vertical Launching System (VLS)

The advanced MK57 Vertical Launching System can accommodate both existing and future missiles for land attack, anti-ship, anti-submarine and anti-air warfare. Its modular electronic architecture allows the Zumwalt Destroyer faster, more economical migration to new missile systems by minimizing the need to requalify the launcher for every new missile, or to modify launcher control software and hardware.

Peripheral Vertical Launch System (PVLS) / Advanced VLS

A system of armored compartments located around the periphery of the Zumwalt. Each PVLS compartment contains and protects one MK57 Vertical Launching System. This design makes launchers and missiles resistant to battle damage while safely isolating them from crew and equipment spaces. Raytheon is teamed up with BAE Systems for the development of the PVLS.

The video clip to the left shows a successful test demonstrating the system’s survivability. Battle damage to the ship is mitigated by projecting the explosion outward.

Total Ship Computing Environment (TSCE)

The TSCE is the first large-scale implementation of the U.S. Navy’s Open Architecture strategy. Designed to bind all Zumwalt systems together, the TSCE creates a shipboard enterprise network allowing seamless integration of all on-board systems. It also gives the Navy increased ability to use standardized software and commercial-off-the-shelf (COTS) hardware on a fleet-wide basis.

Wave Piercing Tumblehome Hull

The tumblehome (inward sloping) hull minimizes the Zumwalt-class destroyer’s radar cross section for enhanced stealth and survivability. Driven by a quiet and efficient all-electric propulsion system, the hull design optimizes speed, maneuverability and stability while minimizing engine noise and infrared signatures.

The Wave Piercing Tumblehome Hull is the responsibility of Northrop Grumman. For more information, visit the Northrop Grumman website.
