Hoga (YT-146/YTB-146/YTM-146) is a United States Navy Woban-class district harbor tug named after the Sioux Indian word for "fish."

Hoga was moored with other yard service craft near the drydocks at 1010 Dock when Pearl Harbor was attacked by Japanese forces on the morning of 7 December 1941.

Pulling in the tow lines that had been chopped free by Vestal's panicked crew, Hoga ran to the assistance of the minelayer USS Oglala, flagship of Rear Admiral William Rea Furlong, commanding Minecraft, Battle Force.

Thomas, aided by another junior officer, conned the ship away as burning oil from the destroyed Arizona began to threaten Nevada.

Just as the second wave of planes struck, the damaged Nevada got underway at 8:45, her officers hoping to escape the trap and run for the open sea through the narrow harbor entrance.

[6] Tied to the port bow, Hoga worked on a raging forecastle fire with the pilothouse monitor and four hose lines for over an hour before retiring.

]Following the Japanese attack, Hoga, along with other yard tugs and support craft, was pressed into additional duty cleaning debris from the harbor and the salvage efforts that began immediately on the sunken and battle-damaged vessels.

[3] Salvage work and heavy duty continued after the war, but in 1948, Hoga was transferred on loan to the Port of Oakland for use as a fireboat through the efforts of Congressman George P. Miller.

Heavy shipping of war material from the Oakland Army Base, an active part of the San Francisco Port of Embarkation, the presence of oil tankers calling at East Bay refineries, and the United States Naval Air Station at nearby Alameda contributed to the wartime significance of the port of Oakland.

The arrangement between the Port of Oakland and the City Council by which the vessel was operated included Port-financed alterations to increase the pumping capacity from 4,000 to 10,000 US gal/min (0.25 to 0.63 m3/s), a berth, new firehouse, and partial defrayment of the salaries of the crew.

According to Mayor Joseph E. Smith, "by this arrangement Oakland will receive excellent fire protection along its valuable waterfront properties, and the cost of the service will be distributed between the City and the Port.

"[9] Arriving in May, Hoga was brought by a Navy crew from Treasure Island to the Grove Street Pier in Oakland, where transfer papers were signed on 28 May 1948.

[10]The day after formal commissioning, Port of Oakland was called into service to help combat a shipboard fire on the freighter Hawaiian Rancher.

The most recent adventure was responding to the burning tanker SS Puerto Rican in the rough seas outside the Golden Gate Bridge on 3 November 1984.

[15] Hoga arrived at Vallejo's Mare Island drydocks (Allied Defense Recycling (ADR) facility) on 31 July 2012 to start work to make the tug seaworthy for its journey to Arkansas.
