Lattice mast

As the caliber and range of ships' guns increased, heavier rangefinders were required, and the powerful guns and engines created shock and vibrations; lattice masts were eventually phased out in favor of the more rigid tripod masts favoured by the Royal Navy.

[3] During 1912, gunnery tests were carried out by the US Navy Department on a lattice or basket mast specially installed on the San Marcos (formerly USS Texas), to see how capable the design was of withstanding sustained gunfire.

Throughout the 1920s and 1930s, the Navy repeatedly found evidence of structural problems in the masts, in large part due to the corrosive effects of funnel gases.

[13] The newer Tennessee and Colorado classes retained their original lattice masts, of heavier construction than those on earlier ships, at the start of World War II.

[15] Two other battleships, the US pre-dreadnoughts Mississippi and Idaho, were sold to Greece in 1914; they retained their lattice masts until their sinking by the Germans in 1941.

Following their experience with the Andrei Pervozvannys, the four Russian Gangut-class battleships, initially designed with lattice masts, were constructed with pole ones.
