Battery Hearn is located on Corregidor Island defending the approaches to Manila from the Manila Bay and the South China Sea. One of two exposed flat trajectory 12" guns, the other being Battery Smith. Formally known as Battery Smith No. 2. Named Battery Hearn.

Built by the U. S. Army to emplaced a 12" M1895A2 gun on a M1917 barbette carriage with a 26 mile flat trajectory range. This gun could traverse 360 degrees. Named Battery Hearn. A spare barrel was placed near the gun. The other exposed battery was Battery Smith.

Wartime History
During the defense of Corregidor by the Americans, this gun was used to fire at Japanese forces on the Bataan Peninsula, but only armor piercing (AP) shells were available making it difficult to inflict serious damage.  The spare barrel was used during the siege in 1942. Prior to the Japanese capture of Corregidor, the gun was disabled by the US Army. 

After Japanese capture, American prisoners of war (POW were asked by the Japanese to put the gun back in to action by replacing the barrel and by salvaging parts from Battery Smith. But, sabotage to its recoil springs mean that it could only be used in a limited capacity.

This gun battery remains intact and is part of the Corregidor Island tour, accessible to visitors.
