Bill.... wasn't there a photo image of a moto tug lashed to the deck on one of the sunken carriers that were found recent? I cannot remember which one it was either Lexington or Hornet. Both sunk prior to 1943. I might be mistaken, but I thought I saw that image.
Tow bars were only used when you had towing equipment.
Tail wheels were pretty fragile things so the tow bar was attached to main landing gear beneath the wings.
Aircraft got too heavy and air wings to big to push around. Tracy provided us with two documents from his research. One dated July 1943 authorizing ships to carry as follows:
CVs- 5 Moto tugs (tractors), 3 Jeeps and 1 LeTourneau Tilly
CVL-2 Moto tugs, 1 Jeep and 1 Kerry Krane (swing arm forklift).
CVE-2 Moto tugs, 1 Jeep and 1 Kerry Krane (swing arm forklift).
The compliment was changed again in Oct of 43
CVs -7 Moto Tugs , 4 Jeeps , 1 LeTourneau Tilly
CVLs 4 Moto Tugs, 2 Jeeps , 1 Kerry Krane
CVEs 3 Moto Tugs, 2 Jeeps, 1 Kerry Krane
The revision reflects the greater availability of this equipment. Prior to spring of 1943 Naval Air Stations and not the line carriers were given priority allotment of this equipment but it did not matter for CVs, CVLs and CVEs did not really start joining the fleet until Spring/Summer 1943.
If you modeling a flight deck prior to Spring of 43 I would say no need for a tow bar as they were probably still pushing, taxing aircraft.
If you wish Jeeps and Moto Tugs in 1/700 (and possibly 1/350) BaconFistModels of Shapeways sells both. Kerry Krane and Le Tourneau Crash Tilly are both sold by SNAFU of Shapeways. Nice 3D printed items. Problem is you have to paint them with acrylic paint.
and TBF Avenger TOWED HOW ? from the forward with tow bars or from the stern tail wheels ....any one ?
