  1. Not quite sure what you mean. see http://nigelef.tripod.com/maindoc.htm Figure 2.
  2. The MLRS installation was the simplest of the lot since MLRS did its own on-board calculation of firing data, just an NIE between the radio and FC computer. BATES used the standard MLRS message set for this, not BATES type messages.
  3. Remembering that the two used in 1945 were both c.20KT, land service nuc weapons were predominantly a lot less than that, although by the late '60s 'dial a yield' was available for at least one system subsequently adopted by several NATO nations.
  4. Technically speaking the prototype L118 should be called XL118, although the British Army has never been overly fussed about this practice. L118 only really refers to the first version that entered service, ie it is the OB approved service pattern. No doubt somewhere there is a MOD(PE) (more likely earlier) instruction about this, and is still valid (the Land Service numbering system was introduced c.1955 before MOD(PE) existed). This is Military Nomenclature 101. Interestingly the subsequent modifications such as fitting the MV radar, digital sights and other mods do not seem to have r
  5. A real antique. They weren't in service long because rapid technical evolution meant the calibre needed went down due to weapon miniturisation. 203 mm and later 155 mm soon became the only calibres use for tactical nukes.
  6. You're a tad off track there mate. The was no '1st generation Light Gun'. Light Gun entered service in 1975, I know this for as fact because at the time I was doing a 12 month course at RSA and did a factory visit to ROF Nottingham, which awash with Light Guns under construction for the Brit Army. Before this the Brit Army used the Oto-Melara 105mm How (Pack How in UK service, introduced c. 1963) and I used these 1965-68 in Borneo and UK. If you are interested in the history of the 105mm Light Gun then see http://nigelef.tripod.com/p_105ltgun.htm . This site knows what it is talking
  7. SANIE (Stand Alone NIE) was used with the BATES specific crypto BID 460 (AKA Palladian), this was the first crypto that CESG produced as software, previous crypto was always in hardware. SANIE was usable with manpack (PRC) radios, ie 320, 351 and 352, as well as VRC. The other NIE was for more complex multi set installations including 432, Warrior, etc with bty CPs, BCs, RHQs.
  8. IIRC there were two TACPs per brigade, each also being a primary FAC. I was under the impression that their vehicle was a LR. In addition there were secondary FACs in various types of unit. Their only specialist equipment would have been a UHF radio (A43), marker panels, and protractor and compass in degrees (instead of the usual mils).
  9. OFG Hogg is the man you need. Pgs 286/7 of his book 'Artillery: Its Origin, Heyday and Decline' has a table giving the key data for all the main field guns in the world in 1910, he lists 25 from 24 countries (everyone made their own guns in those days). For 18-pr and 13-pr: Rds in Limber: 24 Rds in Wagon Limber: 28 Rds in Wagon Body: 48 Rds per gun 176 No of guns per bty: 6 No of wagons per bty: 12 Wt of wagon packed (18-pr): 36.75 cwt Wt of gun (18-pr): 9 cwt Wt of gun & carriage: 24.75 cwt Wt of gun & limber filled: 40 cwt Its also interesting that in developing 18
  10. "Shell are issued plugged & unboxed" Means exactly that. Carts were boxed, fuzes were boxed, shells were plugged and delivered loose, US used a plug with a lifting eye, IIRC UK used a flat plug. May also have been a protective packaging around the driving band, but I may be getting mixed up with 8 inch on that point. Plugged & unboxed was the normal arrangement for medium and heavy arty ammo before ULCs were introduced with FH70 (and the US adopted pallets). In 1941 the only 5.5 shell was 100lbs, the 80lb appeared a couple of years later. The photo of shells in box is od
  11. Not sure when the RO record plate was introduced, early 1950s I think. Obviously it didn't record 'bearings' because these weren't adopted until 1957 and a new pattern of RO plate was then issued. Before bearings the centre of arc was the Zero Line, and ROs (which is what the plate recorded) were angles from it and as any fule no bearings are relative to North. The reference to Troop Pickets is also a clue. ('RO' = Reference Object)
  12. Sorry to spoil a 'good' (but underinformed story, but the GSR makes no mention of Belfast, it does refer to internal carriage in Andover and Chinook, rumour has it that at least one of those is still in use. The other barrel problem was putting the muzzle through the a/c roof when backing/towing it up and down the ramp. Just for the record the Belfast hold could accomodate two LRs side by side, in fact there was room for 8 LWB LRs and 6 105mm Pack Hows, been there, done that, Lt Gun width would not have been a problem. My understanding is that the newer A frame means there is no restrict
  13. All BATES hardware except for the rugged off the shelf hard drive was bespoke, using identical 80C86 processor boards. IIRC the computer had 4 of these and the VDU 1. The basia processing cell (eg BCP) had a computer, 1 VDU, 1 storage device (2 removable hard drives), and two or more Net Interface Equipments of two types, one worked to BID 250 and thence CNR the other had it own integral BID 460 (IIRC).
  14. Unfortunately not, my knowledge is limited to the display at the NZ museum. That said 'The Gunners – A History of New Zealand Artillery’ was publish a few years back and undoubtedly deals with it. Aust also used a couple of btys in NG, but didn't adopt more due to the logistic complications, and perhaps the move of production from UK to India. As well as the two series of UK and India mks, the South Africans also built them (does Selby Engineering mean anything to anyone?) and from the few photos I've seen there do seem to be a few differences. There's a bit about them in Nothlin
