USS John P. Murtha (LPD-26): A Versatile Amphibious Transport Dock

The USS John P. Murtha (LPD-26) is one of the most capable and versatile warships in the United States Navy’s amphibious fleet. Named after the late Congressman John Patrick Murtha, a former Marine and a staunch advocate for the military and defense spending, the ship represents the cutting edge of the San Antonio-class of amphibious transport docks. Designed to support a wide spectrum of operations from combat missions to humanitarian assistance, the LPD-26 embodies the future of expeditionary warfare.

Commissioned on October 8, 2016, the USS John P. Murtha serves with the Pacific Fleet and is homeported in San Diego, California. It enhances the Navy-Marine Corps team’s ability to project power ashore, deploy rapidly, and respond to crises anywhere in the world.

Class and Mission Profile

The USS John P. Murtha belongs to the San Antonio-class (LPD-17) amphibious transport docks. These ships are the centerpiece of the Navy’s Amphibious Ready Groups (ARGs) and are specifically designed to transport and land Marines, equipment, and supplies using a combination of landing craft, amphibious vehicles, and helicopters.

Primary Mission Capabilities:

• Amphibious assault
• Special operations support
• Expeditionary warfare
• Humanitarian assistance and disaster relief (HA/DR)
• Non-combatant evacuation operations (NEO)
• Maritime security operations

This range of capabilities makes the LPD-26 a flexible asset that can operate independently, with a Carrier Strike Group, or as part of a Marine Expeditionary Unit (MEU).

Ship Specifications

The design of the San Antonio-class emphasizes survivability, reduced radar cross-section, and comfort for embarked Marines and sailors. It also incorporates advanced technologies for command and control, aviation, and amphibious operations.

General Characteristics:

• Length: 684 feet (208.5 meters)
• Beam: 105 feet (32 meters)
• Displacement: Approximately 25,000 tons (full load)
• Draft: 23 feet (7 meters)
• Speed: 22+ knots (maximum)
• Range: 7,000+ nautical miles at 18 knots
• Crew: 360 (28 officers, 332 enlisted)
• Embarked Troops: Up to 699 (with surge capacity of 800+)

The ship’s large hull and deck space provide ample room for vehicles, cargo, command centers, and aviation operations, enabling sustained operations ashore.

Aviation Capabilities

The USS John P. Murtha has a full-length flight deck and hangar that support a wide range of rotary and tiltrotor aircraft:

Supported Aircraft:

• MV-22B Osprey tiltrotor aircraft
• CH-53E Super Stallion heavy-lift helicopters
• UH-1Y Venom and AH-1Z Viper utility and attack helicopters
• MH-60 Seahawk for multi-role missions
• Unmanned Aerial Systems (UAS)

The ship features two landing spots and a large aviation maintenance hangar capable of supporting prolonged flight operations. This makes the LPD-26 a critical enabler of vertical lift missions, troop deployment, and aerial resupply.

Amphibious and Vehicle Launch Capabilities

At the heart of the USS John P. Murtha’s mission set is its ability to launch and recover landing craft and amphibious vehicles from its well deck, which can be flooded to deploy surface connectors directly into the water.

Well Deck Details:

• Landing Craft Air Cushion (LCAC): 2 units
• Landing Craft Utility (LCU): 1 unit
• Amphibious Assault Vehicles (AAVs) or Amphibious Combat Vehicles (ACVs)
• Expeditionary Transfer Dock compatibility

Vehicle and Cargo Capacity:

• 25,000 square feet of vehicle storage space
• 35,000 cubic feet of cargo storage
• Can carry Humvees, light armored vehicles, artillery, and other mission-essential ground vehicles

This combination enables the ship to rapidly deploy a full Marine landing force from sea to shore, whether by air or surface.

Command and Control (C2) Capabilities

The USS John P. Murtha is equipped with a sophisticated suite of C2 systems that support a wide range of missions, including amphibious assaults, humanitarian operations, and maritime security.

Key Systems:

• Shipboard Wide Area Network (SWAN) for internal and external data integration
• Integrated Bridge System (IBS) for advanced navigation
• Cooperative Engagement Capability (CEC) for real-time threat sharing
• Command Information Center (CIC) optimized for blue-green coordination (Navy-Marine)

The ship can serve as a command ship for an Amphibious Ready Group or a Task Force, making it a powerful mobile headquarters.

Propulsion and Power

The San Antonio-class LPDs, including the USS John P. Murtha, utilize a diesel-electric propulsion system that provides fuel efficiency, reliability, and reduced maintenance demands.

Propulsion Details:

• Engines: Four Colt-Pielstick PC2.5 diesel engines
• Shafts: Two shafts driving twin propellers
• Total Power: 40,000 shaft horsepower
• Electrical Power: Four Fairbanks Morse diesel generators (2,500 kW each)

This arrangement supports the ship’s propulsion, combat systems, life support, and aviation operations, while allowing for extended range and time on station.

Defensive Systems

While not designed as a front-line combatant, the USS John P. Murtha features a robust defensive suite to protect itself and embarked forces:

Weapons and Defense:

• 2 × Mk 46 30 mm Close-In Guns for surface threat engagement
• 2 × Rolling Airframe Missile (RAM) launchers for anti-air/missile defense
• Chaff and flare decoy systems
• .50 caliber machine guns and mounts for force protection
• Electronic warfare suite with radar warning and countermeasures

The ship’s design includes signature reduction features, such as a sleek hull shape, radar-absorbing materials, and heat suppression systems to lower its detectability.

Accommodations and Habitability

The LPD-26 offers modern accommodations, emphasizing crew comfort and operational efficiency. The ship includes:

• Berthing for 360 crew and 700+ embarked troops
• Messing facilities capable of serving three meals a day to over 1,000 personnel
• Medical and dental clinics
• Gym, recreation areas, and chaplain services
• Spaces designed for long-term deployments

Habitability is a priority for sustained operations in forward-deployed environments.

Operational History

Since commissioning, the USS John P. Murtha has participated in numerous exercises and deployments across the Pacific and Indian Oceans, supporting the Navy and Marine Corps’ forward presence objectives. The ship has participated in:

• RIMPAC (Rim of the Pacific) naval exercises
• Humanitarian assistance missions
• Joint training with partner nations
• Maritime security patrols in the Indo-Pacific

The ship’s versatility has proven vital for adapting to the dynamic nature of modern global maritime challenges.

Legacy of John P. Murtha

John P. Murtha served in the U.S. Marine Corps during the Korean and Vietnam Wars and later became the first Vietnam combat veteran elected to Congress. He was a powerful voice for defense readiness and served as chairman of the House Appropriations Subcommittee on Defense. The ship’s name honors his legacy of service, leadership, and dedication to American military personnel.

Conclusion

The USS John P. Murtha (LPD-26) is a modern embodiment of American amphibious strength and flexibility. With its advanced systems, aviation facilities, amphibious capabilities, and multi-mission versatility, it is an essential component of the U.S. Navy’s ability to respond to crises, protect national interests, and project power from the sea.

Whether conducting humanitarian operations or supporting Marine combat deployments, LPD-26 represents the Navy’s future vision of scalable, adaptable, and lethal expeditionary forces.
