Coat of ArmsThe Shield

Dark blue and gold are the colors traditionally used by the Navy. The Aegis shield highlights the modern weaponry of the USS LASSEN. The blue chevron recalls LT Lassen's service in the coastal campaign during the Vietnam War. It also simulates the prow of a ship, alluding to the first LASSEN's mission as an ammunition ship, which re-armed many of the major fleets. The heraldic sea lion symbolizes the strength and courage, demonstrated by LT Lassen. The chevron suggests the Medal of Honor awarded for LT Lassen's heroism, above and beyond the call of duty, for the rescue of two aviators. The compass rose symbolizes the landing lights of his helicopter, while rescuing the aviators, revealing his position to the enemy, when illumination was lost.

The Crest

The palm fronds suggest the first LASSEN's area of operations in the Pacific; the lightning flashes symbolize striking capabilities and refer to the first LASSEN's service in World War II, rearming many of the major fleets. The trident's three tines represent battle stars earned during World War II in the Pacific as well as denoting the multifaceted offensive/defensive armament of the present DDG 82.


Sea Devils logo

The Lassen Crew are called "Sea Devils". The Sea Devil moniker is taken from HC-7, CDR Lassen's unit during the Vietnam war.

USS Lassen: An Arleigh Burke class destroyer (Flight II-A)

The Arleigh Burke class of guided missile destroyers, one of the destroyer classes of the United States Navy, is built around the Aegis combat system and the SPY-1D multi-function phased array radar. The first ship was commissioned on 4 July 1991. With the decommissioning of the last Spruance-class destroyer, USS Cushing, on September 21, 2005, the Arleigh Burke class ships are the U.S. Navy's only active destroyers.

The Arleigh Burke class are among the largest and most powerful destroyers ever built, both larger and more heavily armed than many previous cruisers. (The larger Ticonderoga class were constructed on Spruance Class hullforms, but are designated as cruisers.) The Arleigh Burke class breaks with previous American construction practices, by being built entirely of steel, rather than having a steel hull and aluminum superstructure. (An aluminum mast is used to reduce topweight). A 1975 fire aboard USS Belknap that gutted her aluminum superstructure and observation of battle damage to British ships during the Falklands War have prompted the decision to employ a steel superstructure.

The class is named for Admiral Arleigh "31-Knot" Burke, the most famous destroyer officer of World War II. Admiral Burke was alive when the class leader was commissioned, and his words to the plankowners echo in the class' distinguished service to date.

Commissioned:  21 APR 2001    Location: Tampa, FL

“This ship is built to fight; you had better know how.”

Class changes in production Flight IIA critical to littoral warfighting effectiveness include the incorporation of embarked helicopters (SH-60R), an organic minehunting capability and the introduction of area theater ballistic missile defense capability to protect near coastal air-fields and seaports essential to the flow of forces into theater in time of conflict. The addition of a helicopter hangar and the upgraded baseline 6.1 AEGIS Combat System are two of the most significant upgrades. The number of VLS cells is increased from 90 to 96, and the Phalanx close-in weapon system is replaced by vertical-launched the North Atlantic Treaty Organization (NATO) Evolved Sea Sparrow missiles when they become available.

The ARLEIGH BURKE class Flight IIA feature a hull lengthened five feet over that of the DDG 51 class. The weight and metacentric height are reduced through using lighter superstructure scantlings. Lower hull plating thickness is increased over 3/4 the hull length amidships. Propellers have improved section to reduce onset of cavitation. The stern wedge (which improves fuel efficiency at cruising speeds) is extended out past the transom. Accommodations are increased for the air group, and have female berthing for four officers, six CPOs, and 18 other enlisted. There is no high-pressure air system; auxiliary power units are used to start the generators. The design uses a commercial slewing-arm davit for the 24 ft rigid hull inflatable boat (RHIB). The computerized Operational Readiness Test System uses one UYK-44 computer with five OJ-454(V)/UYK display consoles in the weapon system equipment rooms. Other changes include the addition of five blast-hardened bulkheads to lessen vulnerability, adding a solid waste management system, and improving the air-conditioning system.
