Ranger Class Tankers

RFA Black Ranger 2At the beginning of World War 2 the Admiralty owned a number of tankers, unfortunately most of these were either small or old, the modern tankers that the Admiralty had started to acquire, the “Dale” class were slow in comparison with those used by the US Navy.  One other drawback attributed to British tankers, was their lack of refuelling capacity, in short for much of the war they could only refuel by the astern method, abeam refuelling was still largely in the experimental stage and not anything like as developed as that used by our American allies, as became quickly apparent when RFA Tankers were first used in the Pacific Fleet Train.

 

The Ranger class were designed by Rowland Baker and were intended to replace the “Belgol” class of 2,000 ton tankers, however as their was a distinct lack of tanker capacity during the war, the “Belgol” class remained in service throughout the war.

The Ranger class were designed by Rowland Baker and were intended to replace the “Belgol” class of 2,000 ton tankers, however as their was a distinct lack of tanker capacity during the war, the “Belgol” class remained in service throughout the war.

The class were designed with the foremast fitted on the starboard bow, the bridge and funnel was offset to port, with a dummy funnel forward of the real one and with an additional canvas deckhouse, all of this was intended to present a silhouette to an attacking U Boat that did not look like a tanker.

 

The Ranger’s were a single deck design with poop and forecastle, with all accommodation and machinery aft.  They were built in two groups; the “Gold” Ranger group were built by the Caledon Shipbuilding Company of Dundee and included “Gold Ranger”, “Gray Ranger” and “Green Ranger”, whilst the “Black” Ranger group were all built by Harland and Wolff at Govan and included “Black Ranger”, “Blue Ranger” and “Brown Ranger”.

 

The Black Ranger group were all fitted with a single 6 Cylinder Burmeister and Wain diesel engine, built by Harland and Wolff with a single screw.  The Gold Ranger group were all fitted with a single 4 Cylinder Doxford Diesel engine with a single screw; all of the class were fitted with two multi tube auxiliary boilers.

 

The class also carried a distilling plant that was capable of producing up to 10 tons of water per day.

 

Cargo capacity in these ships was 2,600 tons of fuel oil, 550 tons of diesel oil and 90 tons of petrol, they had two pump rooms for discharging the cargo, the main pump room had two pumps capable of pumping the oil fuel at 350 tons per hour and the second pump room had a 20 ton per hour pump for discharge of the petrol.  The petrol pump room had a pyrene fire fighting system fitted and the petrol tanks were surrounded by water ballast tanks, in addition to this the deck over the petrol tanks were armoured with 100 lb steel plating.

 

The bridge was also armoured with 4 inch thick plastic plating placed on the front sides and ends of the bridge and 2.5 inch plating on the top.

 

The class were originally fitted for the stirrup method of refuelling over the stern; the stirrup rail ran across the well deck and along the boat deck and could carry around 250 feet of flexible bronze hose.  When they were first launched, non of the class were capable of refuelling by the  abeam method, however later in the war two forty foot derricks were fitted in the forward well, one port and one starboard, with enough 5 inch hose to enable them to undertake this method.

 

During our research into the design of this class it was discovered that the original design included the fitting of a stowage for a small petrol carrying boat, which was intended to be kept in a special stowage on the starboard side of the bow, under the forecastle.  They were also designed to have a wooden spar platform fitted to the after end of the forecastle deck, which was to carry a cased aircraft, though we did not find any record of either of these being used.

 

The armament in the class was a single 4 inch LA gun, one 12 pdr HA/LA gun and two Lewis machine guns as originally built, but this evolved from ship to ship throughout the war and a typical armament fit toward the end of the war would have probably been one 4 inch LA gun, one single 40mm Bofors and four single 20mm Oerlikons.
