USS Ramage (DDG-61)

USS Ramage (DDG-61) is an Arleigh Burke–class guided-missile destroyer commissioned into the United States Navy in April 1995. Named in honor of Vice Admiral Lawson P. “Red” Ramage, a pioneering submariner and Medal of Honor recipient, Ramage combines potent Aegis combat capabilities, high-speed maneuverability, and robust survivability. As part of Destroyer Squadron 23, she routinely deploys in carrier strike groups, expeditionary strike groups, and ballistic missile defense task forces, projecting power across the globe.

Design and Development

Arleigh Burke–Class Heritage

The Arleigh Burke class represents the Navy’s transition to a single multi-mission destroyer design optimized around the Aegis Combat System. Ramage is a Flight I variant, the first production run of this class, featuring the AN/SPY-1A phased-array radar, 90-cell Mk 41 Vertical Launching System, and extensive electronic warfare suites. Lessons learned on early Burkes shaped her survivability features, habitability, and engineering arrangements.

Hull and Structural Features

Ramage’s hull is built from high-strength, low-observable steel with a rounded bow and flared hull sides to improve seakeeping and reduce radar signature. Longitudinal stringers and transverse frames create a shock-hardened structure capable of withstanding mine blasts and underwater detonations. The ship is subdivided into ten watertight compartments, each protected by automatic fire and flooding control valves.

Propulsion and Powerplant

Combined Gas and Gas (COGAG)

Ramage employs a COGAG arrangement with four General Electric LM2500-30 gas turbines delivering a total of 100,000 shaft horsepower. Two turbines drive each controllable-pitch propeller shaft, providing rapid acceleration for high-speed dashes, sustained operation above 30 knots, and single-engine cruising for fuel economy.

Electrical Generation and Distribution

Electric power is supplied by four 1,000 kW ship service gas turbine generators and two 600 kW emergency diesel generators. A dual main electrical bus system, with automatic cross-ties and load-shedding capability, ensures uninterrupted power to radars, combat systems, propulsion auxiliaries, and habitability loads even under battle damage conditions.

Combat Systems and Armament

Aegis Combat System

At the heart of Ramage’s combat capability is the Aegis Baseline 3 system integrated around the AN/SPY-1A radar. The system tracks over 100 simultaneous targets, provides fire-control quality tracks for SM-2 missiles, and fuses data from Link 11, Link 16, and the ship’s sonar arrays. Combat system consoles offer multi-function displays for weapons control, threat evaluation, and tactical decision aids.

Vertical Launching System

Ramage carries 90 Mk 41 Vertical Launch System cells—two 29-cell forward modules and one 32-cell aft module. Typical loadouts include:

• Standard Missile 2 (SM-2) for area air defense
• Harpoon anti-ship missiles
• ASROC anti-submarine rockets
• Tomahawk land-attack cruise missiles

Cells can be replenished at sea via underway replenishment, enabling continuous operations in littoral and open-ocean theaters.

Gun and Close-In Weapon Systems

• A single 5-inch/54-caliber Mk 45 naval gun on the forecastle provides naval gunfire support, anti-surface fire, and limited anti-airburst engagement.
• Two Mk 15 Phalanx Block 1B Close-In Weapon Systems (CIWS) mounted amidships and aft defend against anti-ship missiles and fast-attack craft.
• Two Mk 38 Mod 2 25 mm machine gun mounts offer additional protection against small boats and asymmetric threats.

Anti-Submarine Warfare Suite

Ramage’s ASW suite combines a hull-mounted AN/SQS-53 sonar with an SQR-19 Tactical Towed Array Sonar System. Two triple Mk 32 torpedo tubes allow rapid deployment of Mk 46 and Mk 50 lightweight torpedoes. The flight deck and hangar support one MH-60R Seahawk helicopter equipped with dipping sonar, sonobuoys, and torpedoes, extending detection and engagement ranges beyond the reach of shipboard sensors.

Sensors and Electronic Warfare

Radar and Fire-Control Arrays

• AN/SPY-1A four-face phased-array radar delivers continuous 360-degree search and track capability.
• AN/SPQ-9A/X surface-search and fire-control radar provides high-resolution targeting for surface and low-flying threats.
• AN/SPG-62 illumination radars guide semi-active homing missiles during terminal engagement.

Electronic Support and Countermeasures

The AN/SLQ-32(V)2 electronic support measures suite detects, classifies, and warns of hostile radar emissions. For countermeasures, Ramage carries the Mk 36 Super Rapid Bloom Offboard Countermeasures (SRBOC) launchers deploying chaff and infrared flares. In later upgrades, AN/SLQ-25 Nixie torpedo decoys have been added to protect against acoustic-homing torpedoes.

Communication and Networking

Link 11 and Link 16 tactical data links provide real-time exchange of track data with allied ships, aircraft, and shore stations. An onboard combat network combines inputs from satellites, airborne platforms, and underwater sensors, supporting cooperative engagement with other Aegis-equipped vessels. Secure satellite communications ensure continuous connectivity regardless of theater.

Aviation Facilities

Flight Deck and Hangar

Ramage’s aft hangar and flight deck support one MH-60R Seahawk. The hangar includes maintenance and refueling facilities, parts storage, and a helo-crane for handling large payloads like sonobuoy racks. The flight deck is equipped with deck-edge sensors and elemental wind sensors to ensure safe launch and recovery in high seas.

Unmanned Aerial System Integration

While not originally designed for UAVs, USS Ramage’s aviation control suites and electrical outlets have been adapted to launch and recover the MQ-8 Fire Scout unmanned helicopter. Ship’s boats have also been fitted for launch and retrieval of small unmanned surface vessels for harbor patrol and intelligence missions.

Survivability and Damage Control

Passive Defense

Ramage’s hull and superstructure incorporate degaussing coils to reduce magnetic signature, minimizing vulnerability to magnetic influence mines. Radar-absorbent coatings and angled surfaces suppress radar returns against anti-ship missiles.

Active Damage Control

An integrated Automated Fire and Flooding System continually monitors temperature, smoke, and water ingress. Should a compartment breach occur, electrically actuated dampers isolate the space while remotely controlled firefighting monitors flood fire zones with aqueous film-forming foam. Redundant fire pumps and power buses ensure continued operation under duress.

Crew and Habitability

Ship’s Company and Organization

USS Ramage typically sails with 28 officers and 254 enlisted personnel. Departments include operations, combat systems, engineering, weapons, supply, and medical. Cross-training among watch stations provides redundancy for critical roles, while automated machinery controls reduce watchstanding requirements in engineering spaces.
