The date coincides with the delivery of fearless-class replacement patrol vessels which suggest the new class may include helipads. Recently, ST has also been awarded a contract to supply Oman with helipad-equipped PVs based on the Fearless-75 platform. The weapons fit per Flight report is unclear.
The 6 x RSAF S-70B in service are equipped only with Whitehead torpedoes but can be equipped with Mk-54 torpedoes, hellfire missiles or penguin anti-ship missiles. Hellfire missiles are already used on RSAF AH-64Ds. The Penguin missile has been marketed to RSAF in several prior aerospace events (from Asian aerospace times). Although designed for the LAMPS III helicopters (S-70 derivatives), the 33km ranged missiles are also used on Norwegian & USAF F-16s. A switch to the Mk-54 from the ranged A/S244 whitehead torpedo is not expected. The mod 3 whitehead torpedo has a range exceeding 13km (officially listed as 6km on mindef website) and is in use with 15 navies.
