L.A.B.S. (Low altitude bombing system)

Came across LABS for the first time in ADM 1/27073 (The transfer of Tain Range to the Navy). I have heard of "Toss" bombing but never really thought about it and this file covers the addition of a LABS target to Tain's facilities.
For those that don't know the LABS idea is that the bomb is released during the climb up from the low level attack giving the bomb an artillery type curve. The other related one is the same low approach but the aircraft overflies the target and climbs up and over releasing the bomb at the point where the plane is curving over, again an artillery curve but an extremely odd way of bombing! This was known as "over the shoulder" bombing.
The get a correct bombing solution would have required a more complex bombsight. Something to investigate in the future.

The time frame for this was 1959/60 when the RN were using Lossiemouth.

Thought it might be of interest. Please correct me if my interpretaions are incorrect.

LABS, or Toss bombing ,was one of the modes used by Buccaneers. Which would tie in with the timing at Lossiemouth.

More info about toss bombing, and over the shoulder bombing, here: www.blackburn-buccaneer.co.uk/Pages1_fil...s/0_IntWepSys-2.html

At a place called Meikle Tarrel(I hope Ive spelt that correctly!) near Tain there was a building erected for the coverage of toss bombing. The building was erected in the early seventies and equipped with all kinds of kit for tracking toss bombing, but was never used!

Incidentally toss bombing was a technique for nuclear release.

Dellboy - Yes, the documents refer to the N.A. 39 which became known as the Buccaneer. It also said the Scimitar would be the initial user but expected local objections on account of the "fiendish" noise it made! Anyone care to elaborate?

Canberra - Thanks, you have answered a question as to why there is an "observation post" marked on OS maps at Meikle Tarrel (you did spell it correctly). Why there I wonder, its a few miles from the target which is marked as the northern point of Morrich More? Toss bombing I did connect with nuclear weapons but I assume they were tactical version. The Buccaneer was nuclear capable?

I unstand it was to allow the delivering aircraft time to escape the nuclear blast, but still approach at low level. There is an article in a Boys Book of Flight from that era that has some great diagrams. Will I get the forum in trouble if I scan it and post it here?

The reason for the OP at Meikle Tarrel was to observe the aircraft on the toss bombing runs. Aircraft using target one aka the nuclear target always did their runs from Tarbat Ness, and from Meikle Tarrel you get a superb view of the run in. Incidentally Meikle Tarrel was an Admiralty test site before it was used or should I say not used for tracking aircraft.

You've done it again! That now explains the mystery map. Below is a Google Earth version showing the locations marked on the map and the path over Tarbat Ness. The location are approx but the anomaly is the observation post at Miekle Tarrel which must have been for a later version of the system, especially given it's contruction 10 years later than the map.

In 1957 59 Squadron at Gutersloh had LABS radar fitted in some Canberras. They were normally boxed off in a cardboard cover.
I also believe all four 2TAF Canberra squadrons were similarly equipped.
A number of noisy practice runs used to be made over the airfield with spectacular climb-outs.

Yes, LABS was meant for tactical nuclear weapon delivery which on aircraft such as Buccaneer and the Canberra bomber was delivery of the small bomb of the day Red Beard (nominal 2000 pounds) and later - I assume - the WE177. Carriage and release required an ejector release unit to positively thrust the bomb away from the aircraft; for the Canberra this was pneumatic (compressed gas rams) and as the Buccaneer also had an internal bomb bay it was probably the same. There was no Bombsight per se but the pilot had special instruments to set up the attack profile and release. I don't know what the practice bombing set-up was; it had to have used the standard 25 pound practice bomb or, possibly, the 100 pound PB used for the 'V' Bombers.

PNK, I shall leave it to you to update the Tarbat Ness 'plot' because this is post-war and FAA and confuses the WW2 remains!

Peter at Tain aircraft using target one for LABS when I there tended mainly to be Buccaneers from Lossiemouth and F111s. Bussc used 28lb smoke and flash, the F111s tended to use 6lb bombs. Incidentally one Bucc actually had a DH on the target!
