Visiting forces

The harbour in Bahrain provided some interesting ships to look at, none more so than the flotilla of patrol vessels (couldn't photograph them without arousing a hornets nest!) moored along a quay obviously part of the Kingdom's Naval Base. On an adjoining quay lay an interesting mix of ships including a RN Type 23, an USN "Oliver Hazard Perry" Class Missile frigate (The pennant Number on her bow is 90, but I can't find her in the USN website!), an USN Hydrographic survey vessel and a medium sized Fleet Supply ship also from the USN.

US Navy ships in Bahrain with a RN Type 23 Frigate moored ahead of them.

The Type 23 and the USN Oliver Hazard Perry type pack between them an enormous punch and possess very good anti-missile defence systems. The Royal Australian Navy has several of the "Perrys" in service under the names of their State and Territorial capitals. (For my Ozzie readers, you might like to look up the RAN website where you'll find that HMAS Sydney is pennant Number 03) Both the Type 23 and the Perry Class have powerful gas turbine propulsion systems which allow them to achieve almost 40 knots (the actual speed is not revealed in most reference books) and both can get underway from a berth in around 30 minutes from alert. Manoeuvering is achieved using conventional power modules and the overall power output is further enhanced by being able to vary the pitch on the propeller blades.

Watching one turn under full power is interesting - better hope that no one was trying to drink a cup of coffee or anything else when they do it!

Fleet Auxilliaries such as this are an essential part of any modern fleet deployment - a sort of "one stop shop" for ships!.

By contrast the Fleet Auxilliary is basically a floating department store for ships. Get your fuel, ammunition replacements, food and spare parts here! These ships can steam with others abeam or astern and pass fuel and stores across without havng to stop or find shelter. They are an essential part of any fleet deployment - without them the fleet is tied to fuel ports and bases wherever they go.

The hydrographic survey vessel has multiple roles, but it's most important function is keeping charts and changes to seabeds, coastlines and sea data up to date. Essentially their function has grown from the voyages of the likes of Captain Cook and other explorers - most of whom would have been overjoyed to have some of the modern exploration tools to help them!
