Norwegian destroyers and the coastal-defense mismatch

Norway was a maritime nation with a long littoral, slow coastal-defense ships, and no cruiser force, making capable destroyers a natural requirement. The comparison with Sweden makes the mismatch sharper, because a neighboring northern navy in similar circumstances built more capable destroyers. Motor torpedo boats lacked the range and basing flexibility to cover that geography by themselves. Yet the Sleipner type was closer to an enlarged torpedo boat of under one thousand tons than a fully balanced destroyer. Wartime use as protection for coastal-defense ships and as long-range patrol vessels demanded stronger gun armament and endurance. Experience building patrol craft, small ships, and larger merchant vessels supports the argument that Norwegian yards could have produced a more capable destroyer, even if cost limited the number.
