Modifications to upgrade it to a Third System Fort were begun but never completed. Continuously used through the U.S. Civil War, the Spanish American War, World War I and World War II. Four Endicott Period batteries were installed after the Spanish American War. An additional battery was constructed during World War II. Deactivated 31 Jul 1947 and declared surplus in 1950.

Second System (1808-1816)

Fort Preble was to be rebuilt again as a Third System fort in 1863 with the addition of a single tier of casemates, without a Barbette tier, enclosing the old star fort on three sides. The rear (land side) approach was left open. The old star fort became the Barbette tier covering the front and rear. Two flanking Barbette batteries were to provided an additional 16 guns facing the channel. Only a part of the planned construction was completed.

Confederate raiders entered Portland Harbor on 26 Jun 1863, aboard a captured ship named Archer. The Confederates attempted to escape but 23 raiders were were captured by Union forces and imprisoned at the fort.
