USCGC Joshua Appleby (WLM-556)

USCGC Joshua Appleby (WLM-556) is a United States Coast Guard Keeper-class cutter based out of St. Petersburg, Florida.

History
The Joshua Appleby was commissioned in August 8, 1998. The 6th of 14 Keeper-class cutters, the Joshua Appleby is one of the most advanced cutters currently in the United States Coast Guard's fleet. The Joshua Appleby is named in honor of Sand Key's lighthouse keeper, Joshua Appleby. All 14 Keeper-class cutters are named after lighthouse keepers. The Joshua Appleby' takes for its motto, "The Wrecking Keeper" after Joshua Appleby's very colorful history of shipwreck salvaging.

Mission
The Joshua Appleby's primary mission is the maintenance of over 400 aids to navigation in the Tampa Bay and along the west coast of Florida, including the Florida Keys. Secondary missions include Alien Migration Intercept Operation (AMIO), search and rescue (SAR), and pollution response.

Design
The Keeper-class cutters are the first US Coast Guard cutters equipped with Z-drive propulsion units instead of the standard propeller and rudder configuration. They are designed to independently rotate 360 degrees. Combined with a thruster in the bow, they give the Keeper-class cutters unmatched maneuverability. With state-of-the-art electronics and navigation systems including Dynamic Positioning System (DPS) which uses a Differential Global Positioning System, and electronic chart displays, these buoy tenders maneuver and position aids more accurately and efficiently with fewer crew. The advancement in technology has allowed the crew size to be cut from 24-34 members to 18 members.

Namesake
The ship is named after an American lighthouse keeper remembered for having lost his life in the Great Havana Hurricane of 1846.
