The Russian admiral and explorer Stepan Makarov (1849–1904) designed "Baikal" and "Angara" but they were built in Newcastle upon Tyne, England, by Armstrong Whitworth. They were "knock down" vessels; that is, each ship was bolted together in England, every part of the ship was marked with a number, the ship was disassembled into many hundreds of parts and transported in kit form to Listvyanka where a shipyard was built especially to reassemble them. Their boilers, engines and some other components were built in Saint Petersburg and transported to Listvyanka to be installed. "Baikal" had 15 boilers, four funnels, and was long. it could carry 24 railway coaches and one locomotive on the middle deck. "Angara" was smaller, with two funnels.
