PaulAllen.com    A research team on board the R/V Petrel discovered the wreckage of the USS Hornet CV-8 earlier this month. The team released this photo of one of the Hornet’s 12 five-inch naval guns that defended the ship from air attack. These guns could fire 16 to 20 rounds per minute. The Hornet CV-8 left the Alameda Naval Air Station on April 1, 1942, to carry out the Doolittle Raid. The Hornet was lost on Oct. 26, 1942, after sustaining heavy damage during the Battle of the Santa Cruz Islands.
