US Navy sinks Ex-USS Ingraham frigate during live-fire exercise off Hawaii
The US Navy conducted a sinking exercise off Hawaii on the decommissioned guided-missile frigate ex-USS Ingraham last weekend. The armed forced sank the warship as part of a large-scale military exercise, demonstrating how enemy ships could be targeted in a ‘maritime battlespace’.
Former Navy vessels used in sinking exercises, referred to as hulks, are prepared in strict compliance with regulations prescribed and enforced by the Environmental Protection Agency (EPA).
“Lethal combat power was effectively applied to a variety of maritime threats over the last two weeks in a simulated environment as part of the Navy’s large-scale exercise and expertly demonstrated Sunday with live ordnance,” said U.S. 3rd Fleet Commander Vice Adm. Steve Koehler. “The precise and coordinated strikes from the Navy and our joint teammates resulted in the rapid destruction and sinking of the target ship and exemplify our ability to decisively apply force in the maritime battlespace.”
Each exercise is required to sink the hulk in at least 1,000 fathoms (6,000 feet) of water and at least 50 nautical miles from land and surveys are conducted to safeguard against harm to people or marine mammals during the event.
Ex-Ingraham was a guided missile frigate commissioned on 5 August, 1989, and was decommissioned on 30 January, 2015. The ship was named for Duncan Nathaniel Ingraham and is the fourth Navy ship with the namesake. It is the second of its name to be used in a sinking exercise; ex-USS Ingraham (DD 694), which was decommissioned in 1971 and sold to the Greek Navy, was sunk in 2001.
Prior to being transported for participation in a sinking exercise, each vessel is put through a rigorous cleaning process for environmental safety and is inspected to ensure the ship meets EPA requirements.
