SAN DIEGO – The Ticonderoga-class guided missile cruiser USS Chancellorsville (CG 62) returned to Naval Base San Diego after spending five days underway conducting Advanced Capabilities Baseline (ACB-12) Sea Trials.
Chancellorsville left port on Monday for the first time in nearly a year since starting an Extended Dry-docking Selected Restricted Availability to install the Navy’s most advanced combat system. The crew, along with 76 navy and civilian ship riders, performed comprehensive tests and evaluations of new ACB-12 components.
Systems tested included: the MK 34 Gun Weapon System, which incorporates the new MK 160 Fire Control System, the MK 45 5”/62 Caliber gun, and the AN/SPQ-9B radar set; the Cooperative Engagement Capability system, which allows for high quality data sharing and integrated fire control; the AN/SQQ-89A(V)15 Undersea Warfare Combat System suite, adding the new Multi-Function Towed Array and upgrading the existing hull-mounted sonar; and the Aegis Weapons System Baseline 9A.
The crew also verified Chancellorsville’s sea-keeping and engineering plant reliability by conducting an underway replenishment, an anchoring, man overboard drills, damage control drills, and high-speed steering checks.
Chancellorsville is the lead ACB-12 ship and, as such, is setting the standard for the entire future Aegis Fleet to follow.
