 "AE2" operated in the Sea of Marmora for five days and made four unsuccessful attacks on Turkish ships before being damaged by a Turkish gunboat and scuttled by her crew on 30 April.These attacks are the only occasions an Australian submarine has fired in anger.The Australian submarine service was reformed in 1919, when the British government transferred six J Class submarines to Australia; HMA Submarines "J1", "J2", "J3", "J4", "J5", and "J7".
