Why a land missile may not become a naval weapon

Why was a Sea Streak or naval Starstreak system not widely adopted?

The last announcement in the notes consulted during the discussion described salt-water conversion as prohibitively expensive. A 24-missile naval proposal had been tested, and renewed interest remained possible.

Sea Streak is identified as a tested naval Starstreak proposal for a close-in system holding 24 missiles. The last announcement in the notes consulted during the discussion described salt-water conversion as prohibitively expensive. That assessment is limited to those notes, and renewed interest remains possible. More CAMM, existing Phalanx and investment in lasers appear as competing defensive options. Starstreak's age prompts a comparison with the repeatedly upgraded B-52, illustrating why a design's age alone does not describe its later capability. The missile's division into three smaller projectiles is also suggested as a complication for naval adaptation.
