SANDAKAN CLASS ASUW SHOOTER
Writeup:
A successor of the Admiral Class, the Sandakan Class is named after the capital of the Southern Provinces, and although slightly less capable than the Admiral in the surface to surface role, is capable of defending itself and its battlegroup, which will usually consist of another four of the type, from aerial threats. The Sandakan Class began production in the year of 1960 and production of the class was doubled under the re-armament program of 1963.
The Sandakan Class’s primary offensive weapon system is the GWS.80 cold launch vertical cells, which are rectangular with a length and width of a metre per side and a slanted depth of 11m which allows them to contain some of the most potent anti-shipping weapons on the market. 84 cells make up the total sum of the Sandakan’s GWS.80, an improved model used on the previous Admiral Class Cruiser to great effect. The GWS.80’s improvements come in the form of a more powerful ejection motor, which kicks the missile from the cell before the missile active its engine, and if the engine fails to active the missile falls into the ocean, rather than back down on the deck. It ought to be noted that anti shipping missiles designed to be hot launched – ie, those that use their own engine power to escape the ship’s vertical launch cells, will perhaps need modification before the GWS.80 can fire them.
In addition the Sandakan Class’s anti-shipping arsenal is complemented by two sets of box launchers, each with two quad boxes of the GWS.76 weapons system, a circular missile tube with a diameter of .75m and a length of 7m, capable of independently firing differently sized and configured weapons, resulting in a fully customisable weapons system for the purposes of not just anti-shipping but also anti-submarine missions with a load-out of AS.18S Sea Heron anti-submarine torpedo carrying missiles.
Furthermore, the Sandakan Class is equipped with a modern and accurate gun system, which consists of a pair of PWS.16 75mm 52 cal wing guns, port and starboard, and a single PWS.32 105mm 60 cal gun superfiring forwards, all controlled by the S.492 Targeting Director sensor series. Each 75mm gun is capable of 65rpm and is accurate out to a range of 13km and can elevate to engage aircraft and missiles at a height of 8,000m. The 105mm gun is accurate out to a range of 17km and can engage missiles and aircraft at the same height, with a rate of fire of 55rpm. This enables both guns to excel in the area of shore bombardment or last-ditch missile defence.
Defensively, two missile systems protect the Sandakan Class, and to preserve space, neither are vertical launch, but manage to carry a total of 334 surface to air missiles, a mix of the close range SA.34 and the long range SA.38. Missile systems are guided and targeted by the S.550 Medium Range General Search RADAR and detection is provided by the S.940 Long Range Large Volume Search RADAR. This allows for a long range detection of targets and preparation to lock and engage. It was agreed that a vertical launch system would be more efficient in the role of air defence, but the Sandakan Class is an anti-shipping platform and in any case, is not designed as an AAW picket.
The PWS.40P popup system is the short-range surface to air missile defence system employed by the Sandakan Class. Six launchers are fitted on the ship, and each launcher is capable of firing four missiles before it has to return to its magazine to reload. It takes twelve seconds for a 40P system to reload all four missiles and in total sixteen seconds for it to be once more ready to fire. The PWS.40P aquires illumination from the S.808E E-Band Targeting Array and acquires a firing solution from the S.102 Multirole Target Coordination and Relay Piece which provides networked firing solutions for 360 degree coverage of the ship and in tandem the two sensors, as well as the search radars, can track 460 targets and illuminate 50 for engagement. Targeting takes milliseconds and in a normal EW environment new targets will be locked and targeted by the time a missile has reloaded and often SA.34s fired from the PWS.40P launcher can be fired instantly, the launcher having received a firing solution while reloading. The PWS.40P, when firing the SA.34, has a maximum range of 70km and an engagement range of 55km.
The PWS.64 is a dual arm SA.38 launcher, which feeds from a partially splinter armoured magazine which holds 84 of the missiles. With a maximum range of 400km, the PWS.64 relies on the S.808K K-Band Targeting Array of the S.940 Long Range Large Volume Search RADAR for a longer ranged but less accurate target acquisition. However if the missile or aircraft is within 200km of the ship then the PWS.64 can receive a firing solution using the same methods the PWS.40P system does instead, for a more accurate lock. In fact it is not uncommon for the PWS.64 to track a target using the S.940 and S.808K system then switch to the systems used by the PWS.40P, the S.808E and the S.102, to achieve a firing solution.
For projectile point defence, the Sandakan Class is armed with two PDS.40 40mm six-barrel CIWS and two PDS.48 21-shot rolling airframe systems. The PDS.40 is capable of throwing out 5,000 rounds a minute and is guided by an I/K targeting radar with a range of 45km, which can simulatenously track 24 targets and lock them all by the time they are in range of the weapon’s 3,000 metre and 170 degrees engagement umbrella. The system can traverse 360 degrees in 3.5 seconds (or 170 degrees in 1.65 seconds) and takes 12 minutes to reload after it fires its 2,800 round magazine (33.6 seconds sustained fire). 20 magazines are held below deck and reloading is automatic and conducted by a popup system. The two systems on the Sandakan Class are mounted port and starboard. The weapon can fire sustained fire for its full magazine and cool each barrel collectively during reloading periods but this is not advisable.
The PDS.48 21-shot systems are mounted aft and both have a 200 degree angle of fire from the aft of the vessel, allowing them to engage targets coming head on from both starboard and port angles and of course aircraft from most directions. The PDS.48 uses the S.102 Multirole Target Coordination and Relay Piece to relay information from the ships main sensors to gather target information and can engage at a range of 8 kilometres, each missile having a speed of 500 m/s and a 10kg fragmentation warhead. The system can traverse 360 degrees in 5.5 seconds (200 degrees in 3.05 seconds)
The Sandakan Class is equipped with a full sensor suite, capable of all roles with its long range D/X band radar and E band radars. The S.333D D/X-Band Search Array has a maximum range of 625km for scanning large, fast, and loud targets, and its K-band assistant has an acquisition range of 350km. That said, the S.333D lacks precision and it is likely that until targets are acquired at 350km it will be impossible to determine what targets are. The E-Band radars are much smaller with a maximum range of 200km but are much more accurate.
A number of ESM and RWR antenna and systems dot the ship which ensure that if anything lights up, it will be detected outside of its own detection range. Furthermore, full satellite communications suites mean that the ships weapons and navigations systems can feed directly from satellites if necessary.
The Sandakan uses a conventional engine powered by eight Wilson-Blackburn superheating boilers, with steam provided at 425 degrees Celsius. The power from these boilers goes through four shafts which are powered by single-reduction geared turbines with electrical backup if necessary. Smoke leaves from a pair of smokestacks centreline and the propulsion provides 160,000SHP. Total fuel is carried in six compartments of 800 tons each which totals 4,800 tons of fuel. This provides a maximum speed of 34 knots and a maximum range of 11,000km. The Sandakan’s tunnel stern plus its bulbous bow provide a more streamlined hull, and two rudders assist with maneouvrability.
Tactically, the use of the Sandakan Class is to advance, supported by air superiority and in an anti-air umbrella, to a distance where it can engage via air surveillance enemy vessels with its main missile armament. The Sandakan Class is not a battleship that engages in line combat – she is a true ASuW Shooter.
