U.S. Navy Adds New SPY-6 Arleigh Burke-class Destroyer USS Ted Stevens to Strengthen Air Defense.

The U.S. Navy is adding a new SPY-6-equipped Flight III Arleigh Burke-class guided-missile destroyer, USS Ted Stevens (DDG 128), to its surface fleet, expanding its ability to detect, track, and engage increasingly complex air and missile threats. The destroyer combines the AN/SPY-6(V)1 Air and Missile Defense Radar with the Aegis Baseline 10 combat system, giving the ship a substantially more capable integrated air and missile defense architecture than earlier Arleigh Burke variants.

USS Ted Stevens is being commissioned in Whittier, Alaska, on October 3, 2026, marking its formal entry into active service after delivery, testing, and fleet integration. The ship arrived at its Norfolk homeport on May 15, 2026, beginning its transition from construction to operational testing and fleet integration.

The U.S. Navy USS Ted Stevens DDG 128 is part of the Flight III generation of the Arleigh Burke-class, a configuration centered on the AN/SPY-6(V)1 radar. The U.S. Navy identifies Flight III as the most significant combat-system upgrade introduced into the class, with SPY-6 designed to provide greater sensitivity and improved performance against a broader range of air and missile threats.

This operational change matters because modern naval formations increasingly must defend against mixed attacks involving aircraft, anti-ship cruise missiles, ballistic missiles, and unmanned aerial systems. Greater radar sensitivity and tracking capacity can increase the time available to classify incoming threats, assign weapons, and manage several engagements at once.

The Navy states that the Flight III configuration enables simultaneous anti-air warfare and ballistic missile defense, meeting the need for stronger integrated air and missile defense within the surface fleet. This allows destroyers such as Ted Stevens to protect carrier strike groups, amphibious forces, and other naval formations while also contributing to broader fleet surveillance and missile-defense networks.

Aegis Baseline 10 is the second central element of the ship’s combat architecture. Integrated with SPY-6, it processes radar data, supports threat evaluation and weapon assignment, and connects the destroyer’s sensors with the missile systems used to engage incoming targets. The Navy describes the SPY-6 and Baseline 10 combination as specifically intended to counter evolving threats over the coming decades.

The USS Ted Stevens retains the Arleigh Burke class's multi-mission weapon architecture. The class employs the Mk 41 Vertical Launching System and can use Standard Missile interceptors, Evolved Sea Sparrow Missiles, Tomahawk land-attack cruise missiles, and Vertical Launch Anti-Submarine Rockets, giving the destroyer roles in fleet air defense, ballistic missile defense, land attack, and anti-submarine warfare.

The significance of Flight III therefore lies not in introducing an entirely new missile magazine, but in improving the ship’s ability to detect and track targets and to support more demanding engagement sequences. Better sensor performance can be particularly important when naval forces face multiple threats arriving from different directions, altitudes and trajectories.

The SPY-6 radar also required major changes inside the destroyer. Flight III ships incorporate increased electrical generation and cooling capacity to support the radar and its associated combat systems, reflecting the higher power and thermal demands of the more advanced sensor architecture.

These engineering changes allow the Navy to significantly increase radar and combat-system capability while retaining the established Arleigh Burke hull design. That approach preserves commonality with the existing destroyer fleet while adding a substantially stronger air and missile defense capability.

Ted Stevens will operate from Naval Station Norfolk, Virginia. It arrived there in May after Huntington Ingalls Industries’ Ingalls Shipbuilding division in Mississippi completed construction, marking the start of the ship’s operational integration phase.

The ship is named after former U.S. Senator Ted Stevens of Alaska, a World War II Army Air Corps veteran. It is the first U.S. Navy warship to carry his name, and choosing Whittier for the commissioning reflects the ship’s connection to Alaska.

Flight III begins with DDG 125 and DDG 126 and continues with DDG 128 and later ships, making Ted Stevens part of a broader modernization of the U.S. Navy’s large surface combatant force. The U.S. Navy says the Flight III baseline is specifically intended to meet its requirement for enhanced integrated air and missile defense.

That requirement is becoming more demanding as U.S. naval forces prepare for operations in environments where long-range missiles, unmanned aircraft and coordinated attacks could place surface formations under sustained pressure. In that context, Ted Stevens adds another destroyer that can combine long-range surveillance, missile defense, and multi-mission strike capabilities within the same warship.

The commissioning of USS Ted Stevens therefore represents more than adding another Arleigh Burke-class destroyer. It expands the number of U.S. Navy ships equipped with the SPY-6 and Aegis Baseline 10 combination, strengthening a surface force increasingly dependent on early detection, high-quality tracking, and coordinated missile engagements to defend naval formations in contested maritime environments.
