Newest Guided Missile Destroyer Successfully Completes Combat Trials

SAN DIEGO --- USS Sterett (DDG 104), the Navy's newest guided-missile destroyer, returned from sea Dec. 16 after successfully completing a Combat Systems Ship Qualification Trial (CSSQT) with the newly implemented Aegis baseline 7.1R combat suite.

CSSQT is designed to test the operability of combat systems across all warfare areas while providing an opportunity for Sterett's crew to test the functionality of systems in live-fire tactical scenarios.

Sterett's newly upgraded SQQ-89A(V) 15 sonar system was the first tested with the prosecution of live expendable anti-submarine warfare (ASW) training targets. Further tests incorporated a light-airborne multipurpose system equipped SH-60 helicopter, which dropped sonobuoys and coordinated live torpedo firings.

Additional demonstrations included six test firings of the ship's torpedoes while executing high-speed evasive maneuvers and testing of the Gun Weapon System (GWS).

During GWS tests, the 5-inch gun repeatedly hit a live, aircraft-towed drone, in addition to proving extremely effective as a "layered defense" against highly maneuverable surface threats. The MK38 25MM remotely controlled, gyro-stabilized gun systems, which were used in "layered defense" exercises, were also tested with a beach bombardment integrating Marine Corps spotters that proved highly effective.

"I am extremely satisfied with the gun's performance," said Sterett's Commanding Officer, Cmdr. Brian Eckerle. "It has really performed exceptionally under the taxing demand of firing 582 rounds."

In addition to direct engagement systems, Sterett's Electronic Warfare (EW) capabilities were tried, as were chaff countermeasures and the SPY-1D(V) air search radar. However, the centerpiece of the CSSQT was the live firing of 7 SM-2 missiles against air and ground launched drone targets.

Test objectives for the events, in addition to certifying Baseline 7.1R for tactical use in the fleet, included operability tests of the SM-2 Block IIIB Missile, which contains an infrared (IR) seeker head assembly in the guidance section. The missile has the ability for dual mode terminal homing and can start homing on RF energy, switching to IR homing if necessary for a successful intercept.

In a true testament to the warfighting ability of Aegis Baseline 7.1R, Sterett simultaneously directed four SM-2 engagements to prosecution, and the test was an enormous success. CSSQT was highly anticipated as a critical milestone toward the development and testing of future weapons capability for the next generation of surface combatants.

"Overall, CSSQT was a resounding success," said CSSQT Project Officer Joe Lara. "This is one of the most talented crews I've had the pleasure of working with."

Sterett is homeported San Diego where she arrived in September of 2008. She is the first to operate with Aegis baseline 7.1R: the latest and most capable Aegis operating system. The advanced system orchestrates functionality across the entire combat system suite to include the dual-beam capable SPY-1D(V) radar, an upgraded MK41 Vertical Launch System, integrated Naval Surface Fire Support capability, an upgraded sonar suite and the MK99 Fire Control System.

The 25mm Machine Gun System (MGS) Mk 38 is a 25mm automatic gun system that provides ownship with defensive and offensive gunfire capability for the engagement of a variety of surface targets. It is designed to provide close range defense against patrol boats, swimmers, floating mines, and various targets ashore including; enemy personnel, lightly armored vehicles and terrorist threats. One crewman is required for operation and two for maintenance.

Wow! That is The Shit right there! Those pirates will think again with that thing in the area! Looks like a real high performance machine!

Is it just me or do the geometries of the Sterett look different than on other ships of her class? (Arleigh Burke Class)

Isn't the Phalanx CIWS better weapon than MK-38?

This new weapon is not a CWIS. Some of these new Block IIA destroyers have a phalanx system also, and some don't. They carrry the evolved Sea Sparrow, which is more capable than CWIS against anti ship missiles.

It is different. The stacks are different (in line) and the block IIA ships are about 1000 tons larger and carry hangars for two sh60 helos. The earlier ones could operate helos temporarily, but didn't have hangars.

The class has evolved over time, and there are a number of differences.

I know the MK-38 would be useless against incoming anti-ship missiles but could the Phalanx play the role of the MK-38?

Yes, it does. Obviously bigger, heavier, more deck space, overkill vs small surface targets, takes long time to reload. Just a few thoughts why the navy would substitute the newer weapon for cwis once it wasn't needed for antimissile use. I guess it's all about what you want to fit and maintain on a limited displacement.
