Unusual photos show A-10 attack aircraft built to hunt tanks escorting a ballistic missile submarine

• New US Navy photos show A-10 Warthog attack aircraft escorting a ballistic missile submarine.
• It's unusual to see ground-attack planes built for close-air support and anti-tank missions escorting a sub.
• But it's not unprecedented for the A-10s to participate in maritime exercises.

Newly released US Navy photos captured an unusual sight: multiple US Air Force A-10 Thunderbolt II aircraft — ground-attack planes built for close-air support and anti-tank missions — escorting a ballistic missile submarine at sea last week.
