Hawaii: Today in History 3/25
3-25-1915 1st submarine disaster; a US F-4 sank off Hawaii, killing 21
On 25 March 1915, USS F-4 (SS-23) sank near Hawaii in 300 feet of water due to an acid leak that caused corrosion of the lead lining of the battery, resulting in hull compromise and battery failure. All 21 of her crew were lost. This was the first loss of a manned, commissioned U.S. Navy sub at sea.
