According to Royal Navy website, HMS Astute submarine can use HARPOON. DB3000 only shows it using the UGM-109 TLAM and Spearfish ::

Also, the Valiant class and the Churchill class appears to have had HARPOON capability. See:

The RN Harpoon missiles were withdrawn 2007-2008 [8D]
Will look into the Valiant / Churchill Harpoon capability, thanks!
