Marksman Class (DDL-1915)
Back to Commonwealth Ships List
The Marksman and Later Marksman class leaders were built to act as leaders to
the M-R-S class destroyers of which the Royal Navy ended up with over a 200 of.
The light cruisers that had been being used as leaders to the earlier destroyer
classes were only making 25-28 knots, far too slow to keep up with the 34-36
knot modern destroyers.
The 16 RN leaders were meant to take care of 128 of these, while the Botha and
Talisman class leaders helped out with the rest. The two parts to the
class were differentiated by the 1st batch (Lightfoot sub type) having 4 funnels and the 2nd
batch (Parker sub type) having 3, also the 2nd batch had superfiring forward 4" guns, the first RN
destroyers to do so.
The earlier Marksman were completed 1915-16 and took part in all the major
battles and were used hard along with their destroyer flotillas. Of the eight
ships of the class, one was sunk during WW1 and one was a total loss after
stranding in 1931. The remainder were due to be discarded 1935+ but were
reprieved to become DDEL's, Escort Destroyer Leaders. The escort destroyers had
at least one bank of torpedoes removed, while others lost all of their
torpedoes. The DDEL's kept their torpedoes to give the leader a chance against
any larger targets that might present themselves. The different layouts of the
Early and Later also played a part in the layout and type of armaments to be
fitted, but most of all, the layout of the boiler rooms of the Early ships meant
they could be converted to long range escorts to be able to match the 'R' class
conversions. The early ships had three 4" AA guns fitted along with two 2pd pom
poms and later a pair of 20mm cannons. Removing the fore funnel and boiler room
allowed a bit more space for a larger bridge space so that the ship could act as
Escort Commanders ship if required.
In just three years of war for the Marksman class leaders, the differences are appreciable between the Lightfoot of 1915 and Ithuriel of 1918. The half shield on the 4" has been replaced by the full shield to help protect the crew from splinters. The bridge now sports a director to control the 4". The 3" aft has been removed and replaced with a 2 pounder pom pom for AA work.
The Early Marksman class spent the 1920's and 1930's with their flotillas, going
to lesser and lesser prestigious postings through the years.1934-35 and a
re-emerging German Navy and the failure of the Japanese to ratify the latest
arms Treaty, forced the Admiralty to have a long hard look at what they had and
what might be needed to fight a war at sea against Germany and/or Japan in the
1940's. The last war had shown that Britain's greatest need was to secure its
sea lanes to bring the materials it required flowing in. The convoy and escort
system eventually instituted during WW1 defeated the U-Boat menace to ensure the
flow of materials. From its own submarine fleet the Admiralty was aware that
submarines had evolved considerably during the previous 20 years. Better
batteries, better diesels, made for increased range, length of time at sea and
undersea.
The need for escorts to protect those convoys was of the highest priority. But,
with both Germany and Japan building new battleships, the Admiralty's other
priority had to be the big ships required to catch and dispatch the enemies
raiders. This meant that the older destroyers would have to take up the slack
for the period 1935-45 while new destroyers and destroyer escorts of all kinds
were produced.
The Marksman Class Leaders were split into the Lightfoot and Parker sub classes,
because of the changes made from one to the other. Dimensions remained the same
but the visible differences, described above, were quite marked.
The later Parker type Leaders were short ranged in comparison to the earlier
Lightfoot type. The areas they were to be most involved with was from the UK to
Gibraltar, UK to Iceland, then Iceland to Russia. The remaining ships from WW1
were put through the same WAIR conversion as the later VW class ships. The
leaders being slightly larger than the VW's could fit a bit more aboard. The
Australis ships were also rebuilt to this standard.
The Gabriel and Abdiel were the minelayers of the Marksman class. The armament
was reduced to two 4" and two 2 pounder pom poms, with the torpedoes and two 4"
being removed. Both ships were transferred/sold to Australis being renamed
Meteor and Whirlwind on arrival. These were to be the offensive minelayers for
Australis. The ships were almost unchanged till 1940-41 when the single 2
pounder guns were replaced with twin 20mm cannons.
March 1941 and the current U-boat offensive is taking its toll, the wolfpack
tactics were also proving hard to counter. Escort Groups were formed of 9-10
destroyers and other escorts, with about a third port bound for repair and refit
the escort group usually had about six ships at sea. These groups were not tied
to any convoy but were available to go to the assistance of any convoy. The
groups were also to hunt any U-boats that could be found in the open ocean.
Probably the most successful set of attacks was when an Escort Group came across
the first U-boat in a search line and rolled up the line sinking six U-boats in
a matter of days.

In the 'Fisherless RN' and other scenarios involving the Royal Navy, I
replace the Flower Class corvettes with Flower class Sloops, larger, faster and
more capable, than the corvettes and still able to be built in mercantile yards.
These ships are an uprated Flower class sloop type of the WW1 vintage with 20
years of improvements of technology put aboard.

My original drawings look very ugly compared to the real life drawings above.
The early drawings tend to have a few topweight issues. Drawing turtles.
