Penketh Heavy Anti - Aircraft
Battery Station H17 Barrows Green

The Penketh heavy anti-aircraft gun battery is located on the north side of South lane the A5080 road at Penketh Warrington.

The gun battery was a reused World war 2 site consisting of three 3.7 INCH gun emplacements.

With the cold war looming and the threat of nuclear war by long-range enemy bombers carrying nuclear weapons, it was decided to refit the Penketh gun site out to the 1951 igloo scheme.

Four new 3.7 INCH gun emplacements were constructed laid out in an arc, some of the ww2 emplacements were also reused with the addition of an engine room.

The new post ww2 gun emplacements are eight-sided with two of the sides open for access, four ready to use ammunition lockers were fitted to the side walls, the existing ww2 emplacements had six lockers.

Also constructed were a small crew refuge room and an engine room at each of the four new emplacements.

Each of the engine rooms was fitted with an electric motor driving a hydraulic pump to train the guns and power the automatic loading mechanisms of the gun.

In the centre of each emplacement, was  a gun mounting fitted into the concrete floor to secure the gun called a holdfast.

The original semi-sunken ww2 command post was abandoned and a new command post together with its radar hardstanding was constructed sited to the north-west corner of the site.

The original ww2 generator building and the 2 ammunition magazines will also be reused.

When the site was visited on the 3/ 12/ 2014 the generator building and the2 ammunition magazines appear to be in fair condition and also the semi-sunken command post with its surface features for its instrument positions are still present, and the stairs leading down to the plotting room arrive at the basement to it being heavily flooded out.

The post ww2 command post survives in good condition being used as horse stables, the adjacent radar hard standings are mostly demolished.
 
The seven gun emplacements are each in a variety of condition the northern emplacements being in dense vegetation and tree growth.

The Camp billets alongside south lane where the site entrance is located has been demolished the building foundations are still visible.

Towards the end of WW2 these camp billets were occupied as German & Italian POW and were known as camp 290

The original camp brick water tower is still present, also in this area is a large building which has no military importance it's a disused chicken farm factory.

With more advanced weapons arriving such as the surface to air missiles the site was disused and closed in the early 1960s.

The WW2 Height & Predictor Instruments.

These instruments were located on the roof of the ww2 command post.

The height and range finder instrument consisted of two telescopes placed in a long - base tube.

The operators looked through the eyepieces and pinpointed the aircraft, noting the hight and range, and sent this information to the predictor crew.

The predictor instrument would calculate how far in front of the aircraft the shell should explode to knock the aircraft off course, taking account of the speed as well as the information received from the height and range finder.

The crew would look through the eyepieces and see a small image of the aircraft and turn dials to keep the image in place, and as soon as they were on target, the information would automatically be feed to the gun emplacements.

northern end of the site.

This emplacement has been modified
with the addition of an engine room.


The electrical steel conduit can still
be seen on the right-hand wall.

The WW2 command post was disused when
the new command post became operational.




The post WW2 command post as you can see the
building is now being used as horse stables.

The same emplacement, the world war 2
ammunition Lockers have been retained.

world war 2 emplacements had 6 lockers
and post world war emplacements had 4
.

As you can see the WW2 emplacement has been
modified with the addition of a crew room in
the foreground to the left and an engine
room in the foreground right.




Same emplacement showing the holdfast metal
studs and trunking between the engine room and the gun.


The engine room was installed with an electric motor driving a hydraulic
pump to train the gun and the automatic loading mechanisms of the gun.

The WW2 command post in the foreground to the right was the
predictor and the square open area behind was for the height finder.

In the background can be seen the west ammunition
magazine and the electrical generator building.




These are the steps down to the WW2 semi-sunken plotting room.
