    Default acronyms used in ORBs

    Hello,

    I'm currently reading No. 143 Squadron O.R.B., for September 1944, when they were harrassing retreating German convoys leaving the Channel ports, especially Boulogne-sur-Mer and Calais.

    I'm seeking the help of the forum members because there are some acronyms I don't know at all :
    T.L.C.
    U/C
    U/I
    E/R (a kind of small surface vessel, like the S-Boot ?)
    T.T.A.
    M/V : Merchant Vessel ?
    E/V
    M/S : minesweeper
    And a function quoted once : Nav/W : navigator/Weapons ?

    Thanks in advance

    Joss

    Difficult without knowing the context.
    I'll have a stab at Tank Landing Craft; UnderCarriage (or Under Construction); Under Instruction; Engine Room; TTA - No idea!; Merchant Vessel as you say; Enemy Vessel; Mine Sweeper, as you say; Navigator/Wireless (Operator).....
    if they don't make sense, then I think you'll need to provide the extracts in which they appear, or some clever Pal already knows the answers!!

    Joss/Kevin,
    Never heard of "U/I" being used for Instruction. It was always (in my experience) "u/t" - 'Under Training', and note the lower case letters. The use of capital letters would suggest to me some other decode involving, perhaps, 'Unit/??????'

    If the ORB is talking about enemy vehicles/craft then I doubt TLC is Tank Landing Craft. And the normal abbreviation for this craft was LCT - Landing Craft, Tank.

    Guessing here but how about
    E/V= Enemy Vessel?
    TTA= Time Target Attacked?
    E/R= E or R Boat? These did a similar job to our MTBs and MGBs.

    Depending on the context for your example, but I've seen E/V used for Escort Vessel before.

    Hello

    Thanks all. I thought these acronyms were quite standard. I'll quote the entries to give a context :

    "F/S Johnstone and P/O Warriner attacked 6 probable T.L.C's with unobserved results. F/S Harvey and F/S Haddock attacked 6 T.L.C's scoring a near miss. F/S Barlow and F/S Maddison attacked 6 U/I vessels smoke was seen coming from target and one vessel seems to have disappeared after attack. F/O Gilchrist and F/Lt Bower attacked 15 U/C vessels scroing a near miss on one vessel and the flak ceased from it. On a second sortie the same crew attacked 3 U/I vessels. A near miss was observed by another aircraft. W/O Blake and F/S Knifton attacked 10 possible E/R boats scoring one near miss. F/O Davis and F/S Buckley attacked 5 E/R boats and one T.T.A. - results unobserved."

    Another quote, 25th September : "Photographs show the target in the harbour anchorage consisted of 23 ships (1 M/V Hull 6/800 tons. 1 Rendsburg E/V, 4 M class M/S, 6 tugs (some very heavily armed), 11 trawlers.) Intense accurate light flak was experienced from the shops. P/O Gilchrist, F/S Barlow, F/S Morton-Moncrieff W/O Symons F/O Chamberlain, S/L Fitch and P/O Crocker attacked 3 M/Class M/S in the centre of the formation scoring numerous strikes on all three. F/S Moncrieff, W/O Symons, & Lt Alexandre attacked T.T.S's [sic] scoring many cannon hits. 8/10 balloons were flown by the E/V up to 500 ft. The shipping was dispersed in 3 irregular N-S lines. "A" (S/L Pritchard) was hit early in the attack was pressed home, cannon strikes being obtained on 1 M class M/S, and two T.T.A's. Aircraft "J" saw a fire break out forward on one T.T.A. after "A"'s attack."

    I'm wondering if T is for tug or trawler, and A for armed ?

    I also thought that E/V means enemy vessel, but the line with E/V using balloons opens wide the escort vessel option.

    OK for navigator/Wireless ! Why did I look for something which was so obvious ?

    What about U/I = UnIdentified?
    Would it make sense in the whole text?

    Hello all,

    TTA = Trawler Type Auxiliary, a common abbrevation for armed (escorting) trawlers. In German these kind of vessels are called 'Vorpostenboote'.

    UI = unidentified

    TLC = Tank Landing Craft. The Germans used these kind of square shaped landing craft as swimming flak batteries and are usually called in German 'Artillerie Fähre'.

    E/R Boats are equivalent with the German 'Schnellboote' and 'Raumboote', the first armed with torpedos, the latter not.

    All the best,
    Hans Nauta
