USS Alexandria (SSN-757)


USS Alexandria (SSN-757)
 
The history of the Alexandria as a U.S. Navy warship begins with the staffing of what is known as the Pre-commissioning Unit (PCU) Alexandria. CDR Wilbur Cooke was the Commanding Officer of the Unit. Construction delays necessitated the detachment of CDR Cooke on 6 October 1989, and the assignment of Commander Paul E. Normand in his place on 11 December 1989.

F124 Sachsen class



The F124 Sachsen class is Germany's latest class of highly advanced air-defense frigates. The design of the Sachsen class frigate is based on that of the F123 Brandenburg class but with enhanced stealth features intended to deceive any opponent's radar and acoustic sensors and incorporate also the advanced multifunction radar APAR as well as the SMART-L long-range radar which is claimed to be capable of detecting stealth aircraft and stealth missiles. Although designated as frigates, they are in capability and size comparable to destroyers.
At €2.1 billion for only three ships, this was one of the most expensive ship building programs of the German Navy. They are similar to the Dutch De Zeven Provinciën class frigates.

Heavy Expanded Mobility Tactical Truck


Heavy Expanded Mobility Tactical Truck
 
The HEMTT's objective is to provide heavy transport capabilities for supply and re-supply of combat vehicles and weapons systems for the United States Army. It is distinguished by extreme mobility compared to standard 5-ton trucks, thanks to its large number of wheels and turbo-charged engine, combined with all-wheel drive and very large, low-pressure tires. Though far less publicized than the Humvee, it has been extremely important in transporting logistics behind quick-moving forces based on the M1 Abrams tank.
