  1. Hello Orion (Dirk) hello all May I start by saying a big "Thank You" to Orion for taking an interest in this subject and making the effort to contact the Naval Air Arm Museum in Argentina, without his help I'd still be floundering looking for the information in the depths of the internet, Dank je Dirk. Secondly, I'm sorry for the delay in posting this reply Some of the information received was not in a format that my desktop could handle, this only concerned the pictures, I've had to add my own text as every time I copied a picture it would not include the text. If anybody would like a copy of the original reply please PM me your e-mail and I will gladly forward it to you. So below the reply received from the Argentine Naval Air Museum:- Subject: Grumman S-2E Tracker on board aircraft carrier ARA “25 De Mayo” ESM equipment. Use; For modelling the S-2E Tracker of the Argentine Navy during the Malvinas War In relation with your kind question, first I like to present our apologies for this late answer. The Tektronik 7L3 installation was a urgent measure to cope with the low frequency long range surface radar used by the UK as a primary long range Defense Radar. As you surely know in the S-2E model, we don´t use the upper radome that is present in your S-2A picture, instead the ALD-2B ESM antennas are installed inside the rounded wing tips, see my picture below: http://village.photos/images/user/9772e255-7296-4d31-b6ae-863b8d0d0a86/12a96126-6b9c-494f-bd5a-1b68bfad1639.png These pictures represent the standard combat weapons load, during Malvinas Conflict. The 7L3 antenna, was a blade type, AS-3808/ARC (see picture below) http://village.photos/images/user/9772e255-7296-4d31-b6ae-863b8d0d0a86/30d59e0e-53fa-42a9-8c63-027e80e3c8bb.jpg That antenna was installed on the upper side of the fuselage in between the escape hatches of the sensor operators. http://village.photos/images/user/9772e255-7296-4d31-b6ae-863b8d0d0a86/34b82a88-b90d-4d57-add9-8658ab639fa3.jpg To the right, the Tektronik 7L3. At left a simple laboratory oscilloscope. To connect to the antenna, just a simple video signal cable, http://village.photos/images/user/9772e255-7296-4d31-b6ae-863b8d0d0a86/c46d0730-980e-47f0-800e-91ebd1cd873f.png I hope these information fulfill your request. Ladies and Gentlemen I must apologise I'm no Bill Gates I've followed the procedure I've previously used to insert pictures successfully from Village Photos but I'm sorry to say all I'm getting is the script and not pictures (as you can see). If any of the MODs can help I would be very grateful. RR (Chris)
  2. Good afternoon Dirk PM on its way with my details Regards Chris.
  3. Back in 1982 the Argentine Navy (ARA) realised the Electronic Support Measures (ESM) equipment fitted to their Grumman S-2E Trackers was dated and could only detect radar frequencies in the 1000 ~ 10000 MHz range, quite useless against the P band radar as fitted to the RNs (and others) type 42 Destroyers which operated in the 225 ~ 390 MHz range. They came-up with a war-time solution of installing a Tektronix 7L3 Oscilloscope as used in the laboratory to analysis the intensity/frequency of a radar signal. They fitted the 7L3 in a hard outer case to allow installation in the S-2E. With achieving better than anticipated results when test against ARA Type 42s and other type of ships. The installation of the 7L3 ESM equipment meant the removal of the AN/AQA-4A Sonobuoys Indicator/Analyser/Recorder (Jezebel) system as there was not enough room for both. This meant aircraft were either configured for Anti-submarine warfare (ASW) or the Maritime Surveillance role. Using the 7L3 (and other) equipment S-2E Tracker 2-AS-23 first detected the British Task Force on the 30th April 113 miles to the North of the Falklands/Malvinas Islands My question is for the 7L3 ESM equipment to work it detected radar signals via a specially installed small UHF antenna does anybody have a picture of this UHF antenna please. All the above information is from either: - A Carrier at Risk by Mariano Sciaroni or Wings of the Malvinas by Santiago Rivas or via the internet. As usual any information will be gratefully received.

  4. Hello Mike Just to explain "what's occurring" in Tramatoa's picture and tied-in with Pete in Lincs comment, to help with the process of either spreading or folding Wessex main rotor in high wind conditions the forward lift had a "wind-stop" as shown in the picture. This placed the rotor head just above flight deck level allowing the blades to be walked into position. The process would start and finish as normal with a grubber positioned by the rotor head with two more manning the blade handling pole positioned on the lift, the blade was passed from lift level to the flight deck where the raising of the blade was done by "hands-on". The theory being it was a safer procedure in high winds than trying to balance the blade with the handling pole, with the process reversed for folding. I cant be certain but judging by the deck markings and the clothing worn by the crew I think the photo was taken on one of the early Commando Carriers. If your still awake I hope that was of some interest. All the best RR
  5. Hello all Sorry for the late response but a big thank you to wafu for the reply, now for part two. What I'm after is a photo or two of the Radar and Sonar consuls, also the sonar winch gear/equipment housing for a Westland HAS.1 or even better a HAS.2. I can find plenty of photos showing the above from a US Sikorsky SH-3 but not a Westland HAS. As before any help will be gratefully appreciated. RR (Chris)
  6. Pinky / Pinkies FAA: a tradesman/artificer specializing in radio and radar equipment. Its origin lies in the format of the old RN Aircraft Servicing Form which used pink coloured pages for the radio and radar gear. The MOD Form 700 had/has no such distinction, but the slang for this profession lived/lives on. Gentleman I cant take credit for this, the info comes from "Jackspeak a guide to Royal Navy slanguage" by Rick Jolly and Tugg, (page 215). Hope it helped. Chris. Roof Rat

    VF-41 Bombcat

    Hello I'm looking for some help regarding VF-41s Bombcats September 1995. I know VF-41 were the first USN squadron to drop laser guided bombs in combat using the Tomcat (Bombcat) 5th Sept 95 on a ammo dump in Eastern Bosnia. What I'm after is does anybody know the Modex and Burea Numbers of the two aircraft involved, also the crew rank names, and lastly the type of munitions used. A lot to ask I know but any help would be gratefully appreciated. RR (Chris).

    The best 1/48 F-14

    Having done quite a bit of on line, book and magazine research, and as mentioned above the 1/48 Tamiya seems the best of the bunch currently available (all be it expensive). Here's my question to those in the know :- Can the Tamiya F-14D be back-dated to a B using available market items ? I have the DACO Tomcat book en-route to assist, but any help, pointing in the right direction would be gratefully appreciated. With thanks, RR (Chris). Ps, Happy New Year one and all.
  13. There's a couple from me, having got up close and personal with them for the best part of 8 years working on the flight deck of Ark Royal in the 1970s it's...…..the mighty F-4K Phantom (but I like any Toom). My other choice again through working with them at Portland back in the 70s is the good-old Wessex 1, I use to fly on a regular bases with 772 NAS SARs as a fire-suit-man with a fireball extinguisher underslung . Memories... All the best RR.
  14. Mr H what a sad loss RIP and thank you for all you did. RR
