Question

This vehicle produced an anomalous harmonic sound that Jonesy attempted to analyze with the signal algorithmic (15[1])processing system, or SAPS (“saps”). While looking at photographs of this vehicle, Skip Tyler deduced from an unusual pair of symmetric doors that it was using a tunnel drive system with multiple (15[1])impellers. This vehicle was presumed destroyed after a similar-looking one called the Ethan Allen (15[1])was blown up in a deception operation. An innovative pump-jet propulsion system used by this vehicle, nicknamed the (-5[1])(*) “caterpillar drive”, was reverse-engineered when it safely arrived at Norfolk base. This Typhoon-class vehicle, (10[1])captained by Marko Ramius, was designed to be almost completely invisible to (10[1])sonar. For 10 points, Jack Ryan (10[1])helped (10[1])the U.S. (10[1])government (10[1])retrieve what Russian (10[1])nuclear submarine? ■END■ (10[2])
