||TYPE OF SHIP
||Equipments not capable of SSB voice or RATT
transmitted/received as an F1/FST signal.
||Old ships in reserve or earmarked for disposal.
||640 transmitter and CJK receiver phases A.B.C.D. RWA
included in the later phases. Most ships have had their final
numbers of SSB receivers made up by CJA's instead of more CJK's
||Most ships still in commission in 1963.
||ICS with KMM and full RWA
||All new construction ships 1965-1969
||640 transmitters and base tuned whip aerials.
Full ICS reception and full RWA.
||Standard 3 Mixed
||Types 12, 41, 61 and 81 ships at first long refit
||As for Standard 3A except:- TDC vice TDA. CJM vice
CJA. EY vice EY [better connections]. FSA3 vice FSA1. EZ vice EZ
[containing LF/MF adaptor]. CJN vice B40/41/FAZ and CJC. Modified TCU [1
per TX for both USB and LSB].
||New constructions 1969 onwards. Some items only may
be fitted in earlier ICS ships.
||As for Standard 3B but with ICS reception to Standard
||Types 12, 41, 61, 81 whose next long refit is 1969 or
Three carriers, Hermes, Ark Royal and Eagle were
retrospectively fitted with Standard 3A very early on in this programme so that
they could be viable flagships, and the first four Leander frigates as
well as the first four County class DLG's were up-rated to Standard 3C.
The first ICS fits, surprise surprise, were called ICS1 and that equates to
STANDARD 3A above. Then came ICS2 which was STANDARD 3C, a well
established fit in 1980, and this is the year at which we 'draw stumps'.
1980 is the upper limit for our Museum and whilst we will be looking back to the
times of pre WW1, to explore things like the CWS [Central Wireless System] and
others, we will not meet such a well organised system as that introduced by the
STANDARDS. However, since 1980 the navy has replaced its ICS systems
many times [ICS 20'odd now I believe] and today, 2006, what we started, say, in
1960, has evolved over 46 years into something none of us would recognise,
although I am sure that we would understand the concept and nitty gritty.
