Re: [PSUBS-MAILIST] Back to surface propulsion (generators)

an alternator (meaning an electromagnet generator and not a permanent magnet generator) is used in place of the old PMG because it can produce higher voltage and current at lower RPM

Most US military vehicles and large trucks (tractor/trailer type) are
24 volt. Many Toyota diesel Land Cruisers are 24volt. From what I've heard, alternators are not very effiecent as electrical generators.

Two guiding principles govern Israel Naval Commando doctrine:

1.Every defense system is vulnerable.

2.The enemy can deal with weapons and operational methods that are known; for that reason, naval commandos use imagination, daring and initiative, to create situations which cannot be anticipated.
