Design

The Public Works Administration authorized the manufacturing of the Yorktown class in 1933. In 1938 the USS Hornet was authorized.

The Yorktown class owes it's design to experience that the United States fleet obtained during maneuvers in the 1930s. Also it was felt that a carrier needed more protection.

Torpedo Protection

There were two tanks with water and one empty tank that were along the hull and under the waterline that were intended to absorb the explosion of a torpedo.

Hangar Deck

Around the hangar deck were roller shades that could be opened so that aircraft could be warmed up before being brought up to the flight deck. This also allowed for the dissipation of fuel vapors.

There was a catapult in the hangar deck.

Flight Deck

There were three 15,000 lb elevators and two catapults in the Yorktown class. The deck was made of 6" wood planks.

Island

The island on the Yorktown was the first American carrier to contain the smoke stack.

Defenses

The 5" L/38 dual purpose guns were first installed on the Yorktown class.

In front and behind the island were four 1.1" quadruple gun mounts. On the gallery deck were 24 .50 cal machine guns.

Cost

Cost approximately $25 million.

In March 1942 the USS Hornet loaded 16 B-25 bombers and sailed for Japanese waters where on April 18, 1942 launched the B-25s in a raid on Japan. The USS Enterprise provided escort.

Coral Sea

The USS Yorktown and USS Lexington participated in the first carrier vs. carrier battle on May 8, 1942. Dive bombers from the Yorktown hit the Shokaku two times.

On May 8, 1942 the Japanese carrier Shoho was sunk within 10 minutes. Dive bombers from the USS Yorktown damaged the Zuikaku.

A bomb penetrated the flight deck of the USS Yorktown and exploded wounding or killing 66 crew members.

Midway

Despite the damage to the Yorktown it was repaired in three days and was able to join the Enterprise and Hornet near the island of Midway. The American forces located the Japanese carriers first and launched an attack. Three carriers were destroyed in the initial attack. Dive bombers from the Enterprise sunk Akagi and Kaga. The surviving Hiryu launched a strike that hit the Yorktown with three bombs and two torpedos. Eventually the I-168 was able to hit the Yorktown with two more torpedoes and she sank.

Aircraft from the USS Hornet damaged the cruisers Mikuma and Mogami.

Eastern Solomons

In support of the landings at Guadalcanal the Enterprise was hit by three bombs in the Battle of the Eastern Solomons. The Enterprise returned to Pearl Harbor for repairs.

Santa Cruz

The USS Enterprise and USS Hornet took part in the Battle of Santa Cruz. Aircraft from the Hornet did damage the Shokaku. The Hornet was hit by two torpedoes, three / six bombs, and two kamikazis. That same day the Hornet was hit by another torpedo and two more bombs. The crew abandoned ship and US destroyers shot nine torpedoes and 400 / 430 rounds into the Hornet but it took four torpedoes from Japanese destroyers to sink her.

On October 26, 1942 the Enterprise was hit by two bombs.
