Military Modelling 02 2005


Have you ever wondered what a nuclear bomb looks like? If you have, then you'll be interested to see one of the exhibits at the Fleet Air Arm Museum. Situated on the flight deck of their HMS Ark Royal Aircraft Carrier Experience is a somewhat modest looking green bomb positioned close to a Buccaneer aircraft. The bomb is a Type WE177A nuclear weapon and it was in service from 1996 - 98. Bombs like this were deployed to the aircraft carriers Victorious, Hermes, Eagle and Ark Royal (IV). The bomb is, of course, now disarmed but during service, its payload was 200 kilotons (10 times the destructive power of the bomb dropped on Hiroshima) and enough to wipe out a city the size of Greater London and render it uninhabitable for many years. The bomb had four detonation options. Detonated at altitude. A radar-activated altimeter could be set to detonate at say 1,000 feet above ground for maximum blast devastation. Detonated on impact with the ground where the blast damage would be less far reaching. Detonation at a specific depth at sea for the destruction of enemy submarines.

Now that you have a sturdy base in place, it's time to lay your track. It does not matter what brand or code rail you choose, but properly laying your track is critical for good, smooth operation. This is the time to recheck your roadbed to ensure it is smooth and well supported. If you have grades on your layout/module, double check to ensure the start and end of each grade is smooth enough that the vertical rise of the track will not result in the bottom of your locomotives' pilots coming in contact with the rails (this results in sudden, unwanted stops, short circuits or both). Once you're sure there will be no unfortunate circumstances, it's time to begin. I lay my track differently than most. I use contact cement to hold down the roadbed and track. I use it wet so I can slide things into final alignment before the contact cement "grabs it." This gives me a certain amount of flexibility and avoids any thought of using any kind of nail. Push pins, yes; nails, no. In any case, I recommend you glue the track to your roadbed with good quality glue, such as Aleen's Tacky Glue. The tack of this glue will help you get things down in place without it slipping around. Apply the glue and then brush it out so there is a thin bed of glue to attach your roadbed. Pin your roadbed in alignment and let the glue dry.
