She is named after US Marine Corps corporal Jason Dunham, who was posthumously awarded the Medal of Honor for service in the Iraq War.[1] She was built by the Bath Iron Works in Bath, Maine.[5] She was christened by Corporal Dunham's mother, Debra Dunham, the ship's sponsor, and launched on 1 August 2009.[1] Jason Dunham was commissioned on 13 November 2010.[3]

Ship's history

[edit]

In May 2022, Jason Dunham was homeported out of Naval Station Mayport and a part of Destroyer Squadron 28, along with Carrier Strike Group 8 led by the aircraft carrier USS Harry S. Truman.[6]

In August 2025, Jason Dunham sailed for Venezuela and the Caribbean Sea. The destroyer was among the warships ordered to the area to combat drug smuggling traffic. On 4 September, in response to the presence of U.S. Navy warships in the region, two Venezuelan F-16 fighter jets conducted a flyover of Jason Dunham,[7] after which Trump gave permission to shoot down Venezuelan planes if they presented a danger to U.S. ships.[8]

USS Jason Dunham (DDG-109) is an Arleigh Burke-class guided-missile destroyer in the United States Navy, named for Corporal Jason L. Dunham, a Marine awarded the Medal of Honor posthumously for sacrificing himself to protect his comrades during combat in Iraq. The vessel, built by General Dynamics Bath Iron Works and commissioned on 13 November 2010, serves as a multi-mission surface combatant equipped with the Aegis Combat System for air defense, anti-submarine warfare, and anti-surface operations. Homeported at Naval Station Mayport, Florida, the destroyer has conducted deployments to the U.S. Fifth and Sixth Fleet areas, participating in carrier strike group operations, live-fire exercises, and replenishment-at-sea evolutions to advance maritime security and deterrence. In 2025, Jason Dunham returned from a nearly nine-month deployment with the Harry S. Truman Carrier Strike Group, transiting key chokepoints like the Suez Canal and supporting allied interests in contested regions. The naming honors Dunham's actions on 14 April 2004 near Husaybah, where the 23-year-old corporal covered an insurgent's grenade with his helmet and body, enabling two Marines to escape unharmed at the cost of his life nine days later; he became the first Marine Medal of Honor recipient for Operation Iraqi Freedom.

Corporal Jason L. Dunham's Background and Heroic Action

Corporal Jason L. Dunham was born on November 10, 1981, in Scio, New York, where he lived his entire early life with his parents and siblings before graduating from Scio Central School in 2000. That year, he joined the , completing recruit training at Marine Corps Recruit Depot Parris Island on October 27, 2000, and initially serving as a security force sentry. By 2004, Dunham had risen to the rank of and was assigned as a rifle squad leader in the 4th Platoon, Company K, , Regimental Combat Team 7, , based out of . On April 14, 2004, during Operation Iraqi Freedom, Dunham led his squad on a reconnaissance patrol in Karabilah, —near the Syrian border—following an insurgent attack on a Marine convoy. After engaging and subduing several insurgents in close-quarters fighting, one enemy fighter produced a ; Dunham directed his to secure the other prisoners while positioning himself to cover the device. He placed his helmet over the grenade and threw his body atop it, absorbing the fragmentation blast that detonated immediately, thereby saving the lives of at least two fellow in his immediate vicinity. The act demonstrated deliberate under direct threat, as the grenade's proximity ensured his fatal wounding while shielding others from lethal injury. Dunham sustained severe shrapnel wounds to the head and body, leading to a medically ; he was evacuated to the National Naval Medical Center in , where he died of his injuries on April 22, 2004, at age 22. For his actions, he was posthumously awarded the on January 11, 2007, by President in a ceremony, becoming the first Marine Corps recipient since the and the first for service in . The Navy recognized his valor across services by announcing on March 23, 2007, that an Arleigh Burke-class , DDG-109, would bear his name, honoring the inter-service tradition of commemorating exceptional combat sacrifice.

Keel Laying and Launch

The keel of the Arleigh Burke-class guided-missile destroyer USS Jason Dunham (DDG-109) was laid down on April 11, 2008, at General Dynamics Bath Iron Works in Bath, Maine, marking the formal start of hull assembly using modular construction methods proven effective across the class's production run. The ship was launched on August 1, 2009, entering the water for the first time after hull completion, and was christened during a ceremony that day by Debra Dunham, mother of the namesake Corporal Jason L. Dunham, in accordance with U.S. Navy tradition honoring Medal of Honor recipients through family sponsorship. Post-launch fitting out at included installation of propulsion systems, combat electronics, and vertical launch systems, demonstrating the shipyard's capacity for integrating complex weaponry within a 21-month build timeline from to float, consistent with empirical efficiencies in -class fabrication that have yielded over 70 hulls since 1991 without major program delays.

Delivery and Commissioning Ceremony

The USS Jason Dunham (DDG-109) was delivered to the U.S. Navy by Bath Iron Works on June 4, 2010, following successful sea trials that verified her operational readiness after construction. The ship's commissioning ceremony occurred on November 13, 2010, at Port Everglades in Fort Lauderdale, Florida, marking her formal entry into active service as the 59th Arleigh Burke-class destroyer. Principal speakers, including Marine Corps representatives, emphasized Corporal Jason L. Dunham's selfless sacrifice in Iraq and the vessel's embodiment of that valor in modern naval deterrence and power projection. The event drew attendees honoring the shared November birthday of Dunham and the Marine Corps, with proceedings including the reading of the commissioning orders, the ship's bell ringing, and the crew's assumption of duties under Capt. Michael J. Donley. Post-commissioning, the destroyer transited to her assigned homeport at , , arriving in early 2011 for initial outfitting and crew integration. Early operations focused on basic qualifications, systems familiarization, and certification to ensure seamless transition to fleet tasking, with the crew achieving proficiency in core functions ahead of shakedown activities. This phase reflected efficient handover from builder to operator, with no significant delays reported in the commissioning timeline.

Design and Capabilities

Arleigh Burke-Class Specifications

The Arleigh Burke-class destroyers in the Flight IIA configuration, such as USS Jason Dunham (DDG-109), have an overall length of 509.5 feet (155.3 meters), a beam of 66 feet (20 meters), and a draft of 31 feet (9.4 meters). These vessels displace approximately 9,200 long tons at full load. The standard crew complement includes 23 officers and around 300 enlisted personnel, supporting extended independent operations. Propulsion is provided by four General Electric LM2500-30 gas turbines delivering a total of 100,000 shaft horsepower through a dual-shaft arrangement with two controllable-pitch propellers. This configuration enables sustained speeds exceeding 30 knots, facilitating rapid response and blue-water power projection across oceanic theaters. Flight IIA ships serve as versatile multi-mission platforms optimized for anti-air warfare, anti-submarine warfare, and surface warfare, while integrating into carrier strike groups for layered defense and offensive strike capabilities. Key enhancements over prior flights include enlarged flight decks and enclosed hangars accommodating two MH-60R or MH-60S helicopters, which bolster anti-submarine and surface warfare versatility through embarked aviation detachments.

Armament, Sensors, and Propulsion

The USS Jason Dunham (DDG-109), as a Flight IIA Arleigh Burke-class , features a Mk 41 (VLS) with 96 cells configured to deploy a mix of missiles for multi-domain threat engagement, including BGM-109 Tomahawk land-attack cruise missiles for long-range precision strikes, RIM-66 Standard Missile-2 (SM-2) and RIM-174 Standard Missile-6 (SM-6) for extended-range air and defense, RIM-162 Evolved SeaSparrow Missile (ESSM) in quad packs for medium-range point defense, and Vertical Launch Anti-Submarine Rocket (VLA) for underwater threat neutralization. These systems enable the ship to conduct simultaneous offensive and defensive operations, with the VLS's modular design allowing rapid reload at sea or in port to sustain firepower in prolonged engagements against peer-level adversaries. Complementing the VLS are two Mk 141 quad launchers for RGM-84 Harpoon anti-ship missiles, providing over-the-horizon surface strike capability, though their role is diminishing with the introduction of over-the-horizon weapons like the . The ship's primary gun is a Mk 45 5-inch/54-caliber turret for and anti-surface engagements, supported by two triple Mk 32 tubes firing Mk 46 or Mk 54 lightweight torpedoes for close-range , and two Mk 15 Close-In Weapon Systems (CIWS) with 20 mm Gatling guns for terminal defense against incoming missiles and aircraft. Sensors are centered on the AN/SPY-1D(V) multi-function phased-array radar integrated into the Aegis Baseline 9 Combat System, which supports 3D air search, track-while-scan, and fire control for up to hundreds of simultaneous targets, including ballistic and hypersonic threats, with demonstrated effectiveness in neutralizing simulated anti-ship ballistic missiles during exercises like the 2002 Aegis BMD test series where SPY-1 achieved its first successful intercept. This radar, paired with AN/SPG-62 illuminators for semi-active homing missiles, enables cooperative engagement capability (CEC) for networked warfare, allowing data sharing with allied assets to extend the battlespace against advanced air-denial systems employed by Russia and China. For anti-submarine warfare, the ship employs an SQQ-89 integrated suite incorporating AN/SQS-53C hull-mounted sonar and AN/SQR-19 tactical towed array sonar, facilitating detection and localization of submerged threats at extended ranges through active and passive modes. Propulsion is provided by four LM2500-30 gas turbines in a combined gas turbine (COGAG) arrangement, delivering 100,000 shaft horsepower to two shafts with controllable-pitch propellers, achieving sustained speeds exceeding 30 knots and a range of approximately 4,400 nautical miles at 20 knots, which supports persistent presence and rapid maneuver in contested littorals without reliance on vulnerable fixed . This configuration, with redundant systems and advanced , enhances and operational tempo, allowing the to evade detection while projecting power against high-end threats, as evidenced by class-wide in multi-week exercises simulating peer conflict scenarios.

Operational History

Shakedown and Early Exercises (2011–2013)

Following its commissioning on 13 November 2010 at , , USS Jason Dunham transited to its homeport at , , where it began post-commissioning operations and integration into the U.S. Atlantic Fleet's surface force structure, including assignment to Destroyer Squadron 28. In early 2011, the destroyer conducted initial certification exercises off the U.S. East Coast, culminating in the successful completion of Combat Systems Ship's Qualification Trials (CSSQT) on 25 March alongside USS Gravely (DDG-107); these trials validated the ship's combat systems through live-fire missile engagements and other evaluations, supported by personnel. On 25 August 2011, Jason Dunham executed an emergency sortie from Norfolk to evade , demonstrating early operational responsiveness without reported complications. In 2012, the ship advanced to advanced training phases, departing Norfolk on 19 March for Group Sail exercises as part of the USS Dwight D. Eisenhower (CVN-69) Carrier Strike Group, focusing on coordinated surface and air operations to build baseline readiness. This was followed by participation in Composite Training Unit Exercise (COMPTUEX) starting 24 April, which integrated Jason Dunham into carrier strike group tactics; exercises included visit, board, search, and seizure (VBSS) drills on 9 May, emphasizing hands-on proficiency in maritime interdiction and force protection scenarios. These evolutions, conducted without significant incidents, certified the crew's compatibility with joint carrier operations and highlighted the effectiveness of structured Navy training in achieving full mission capability within approximately 18 months of commissioning. Early port visits, such as a four-day Midshipmen Cruise departing on 9 (likely 2011), further honed junior officer and enlisted skills through at-sea familiarization drills. The absence of major safety or performance lapses across these phases empirically affirmed the robustness of post-delivery shakedown protocols for Arleigh Burke-class destroyers, enabling seamless transition to deployment readiness by mid-2012.

European and Mediterranean Deployments (2014–2018)

In 2014, USS Jason Dunham participated in NATO's Joint Warrior 14-2 multinational exercise, departing Naval Station Norfolk to conduct operations in European waters focused on enhancing interoperability with allied forces. This exercise, held off the coasts of the United Kingdom and Scotland, involved joint training in air, surface, and subsurface warfare scenarios to strengthen deterrence and collective defense capabilities amid heightened regional tensions following Russia's annexation of Crimea. The destroyer undertook a seven-month deployment to the U.S. 6th Fleet area of responsibility in early 2015, entering the fleet's operational zone on March 4 to support maritime security and freedom of navigation operations in the Mediterranean Sea. Routine operations were conducted in the Mediterranean, including documented activities on March 18, emphasizing presence and readiness. A scheduled port visit to Bar, Montenegro, from March 13 to 16 allowed for bilateral engagements to build partner capacity before transiting to the Black Sea in early April for stability-promoting operations, exiting the region on April 14. In June 2015, joined Baltic Operations () 2015, a NATO-led exercise involving 17 nations to demonstrate alliance cohesion and high-end warfighting integration in the . The deployment concluded with port visits to , (June 28); , (July 17); and Plymouth, (July 31), where crew interactions reinforced deterrence signaling and with European allies. The ship returned to on August 28, 2015, after operations that underscored U.S. commitment to NATO's eastern flank. In 2018, deployed as part of the to the 6th and 5th Fleet areas, initiating operations in the European and Mediterranean theaters before transiting south. This forward presence supported alliance-building and counter-proliferation, highlighted by the August 30 interdiction of a stateless in the carrying 2,521 rifles, 34 launchers, and other illicit arms destined for regional instability. The action, involving over 200 personnel in boarding and inspection, demonstrated the destroyer's role in disrupting arms flows threatening Mediterranean-adjacent security. The deployment ended with return to on December 21, 2018.

Caribbean and Global Operations (2019–Present)

In August 2025, USS Jason Dunham deployed to the southern as part of a U.S. naval buildup under U.S. Southern Command to counter drug trafficking networks, operating alongside guided-missile destroyers USS Gravely (DDG-107) and later USS Stockdale (DDG-108). The deployment emphasized maritime interdiction of narcotics routes from and transit zones, enhancing detection and disruption capabilities without primary reliance on ground-based assets. On September 2, U.S. forces executed precision strikes on suspected drug smuggling vessels while Jason Dunham and Gravely maintained presence in the area, contributing to a series of operations that included seizures and detentions of traffickers. Regional tensions escalated when two Venezuelan F-16 fighter jets performed a low-altitude flyover near Jason Dunham on September 4, 2025, prompting U.S. characterization of the maneuver as provocative and leading to the deployment of additional F-35 jets for air defense and strike support. The ship's operations continued into October, bolstering hemispheric security against cartel-enabled migration and smuggling threats, with U.S. naval assets in the region facilitating multiple interdictions that disrupted tons of contraband flows. These efforts underscored the destroyer's role in forward presence missions, leveraging capabilities for surveillance and rapid response in support of broader border security objectives.

Notable Operations and Achievements

Weapons Interdictions and Counter-Narcotics

On August 28, 2018, the USS Jason Dunham (DDG-109) conducted a operation on a stateless in the , approximately 70 nautical miles off Yemen's coast, intercepting an illicit shipment of 2,521 automatic rifles concealed in plastic-wrapped bundles inside green burlap sacks. The rifles, originating from an undetermined source and likely bound for non-state actors such as Houthi rebels or Somali militants, were offloaded and inventoried aboard the ship, with investigators later confirming their illicit nature and markings inconsistent with legitimate arms transfers. This interdiction disrupted potential arms flows to terrorist groups and criminal networks, denying thousands of small arms that could fuel regional instability and violence. In counter-narcotics efforts within the U.S. Southern Command (SOUTHCOM) , Jason Dunham participated in maritime interdictions targeting Venezuelan-origin vessels in the during 2025 deployments. On September 14, 2025, the ship's boarding team detained a Venezuelan-flagged suspected of narcotics trafficking, detaining nine crew members for transfer to U.S. authorities, though Venezuelan officials contested the action as occurring in their . Earlier that month, Jason Dunham deployed an armed team to occupy a suspected for eight hours, securing it without lethal force amid broader operations against cartel-linked "narcoterrorist" vessels. These engagements supported allied handoffs to partner nations and contributed to denying routes, with the ship's presence in multinational patrols enhancing deterrence against transnational criminal organizations responsible for and flows into the .

Training Excellence and International Partnerships

Following the 2017 Board of Inspection and Survey (INSURV) assessment, which evaluated the ship's material condition and operational readiness for demanding environments, USS Jason Dunham emphasized advanced damage control training to enhance crew proficiency in crisis response. In 2018, the crew conducted intensive "Damage Control December" drills, transitioning to weekly "Warrior Wednesdays" sessions that incorporated scenario-based simulations for firefighting, flooding response, and casualty evacuation, fostering realistic preparation for survivability in combat or accidents. These efforts culminated in practical applications during general quarters drills, where sailors practiced damage control tactics under simulated high-stress conditions in the Atlantic Ocean. The ship's training regimen contributed to operational certifications and awards recognizing engineering and weapons system excellence. In , USS Jason Dunham received the Close-In Weapons System (CIWS) Excellence Award for superior maintenance and crew performance in close-defense capabilities, reflecting rigorous drill outcomes. Such achievements underscored sustained readiness, with INSURV results demonstrating high scores in self-assessments and material inspections that validated the effectiveness of integrated training programs. International partnerships bolstered through joint exercises and port engagements. In February 2022, USS Jason Dunham collaborated with the Egyptian Navy ENS during International Maritime Exercise/Combined Exercise (IMX/CE) 2022 in the , conducting maneuvering operations, communication drills, and tactical formations to improve multinational coordination against regional threats. Complementing this, a scheduled port visit to Durres, , in May 2022 facilitated bilateral exchanges on , enhancing NATO-aligned cooperation in the U.S. Naval Forces area. These activities strengthened readiness metrics by standardizing procedures and building trust among partner navies.

Command Accountability Issues

2013 Relief of Key Personnel

On December 20, 2013, Commander, Destroyer Squadron 28 relieved the of USS Jason Dunham (DDG-109), Cmdr. Kenneth W. Rice, and the command master chief, Stephen Vandergrifft, of their duties due to a loss of confidence in their ability to perform those roles. The relief occurred while the ship was conducting routine operations at its homeport of , , with no reported effects on vessel safety, crew welfare, or ongoing mission readiness. A investigation determined that Rice and Vandergrifft had mishandled reports of incidents aboard the ship, including inappropriate responses to allegations and failure to promptly notify chain-of-command authorities as required by . Specifically, the probe revealed prior events, such as a directing 19 female enlisted sailors on October 15, , to carry buckets of from non-operational toilets during a exercise, which went unaddressed at the senior enlisted and levels. Both officers received for their lapses, marking a direct application of the U.S. 's accountability protocols to senior leadership positions. The incident underscored the 's emphasis on swift intervention in command failures to maintain operational standards, as reliefs of this nature are rare and typically reserved for substantiated deficiencies in oversight or ethical judgment. No additional public details on the investigation or subsequent assignments for and Vandergrifft were released by the , consistent with standard procedures for administrative actions short of courts-martial. This event remains the only documented relief of key personnel in the ship's to date.
