All four vessels are same. There have been some updates in super structure following the choice of AAW package, but all these changes have been implemented already.
This is above of me why waste tons of solid iron into the see , but not recycling that iron for new ones .
It’s hard to get proper naval targets to do exercises on, so using these as targets give valuable training and insight, moreover it’s not a waste, these sinkings are actually good for the environment. All fuel and other useful or hazardous material is removed prior to sinking, the metal hull becomes an artificial habitat for many marine animals. There’s hundreds of artificially made reefs with tanks, ships, aircraft and other hulls in the ocean.
You are totally right , but my point why we are wasting tons of iron, we can use the iron for construction of new ship, even not war ship .. it can used for commercial ship
Ship hulls have a life, the iron on them cannot be used infinitely as overtime small but fatal cracks and impurities develop in them, these ships are now so old that the material likely isn’t usable without major repairs, at which point it would be easier to get new iron. Plus everything else in the ship is stripped, it’s just an empty skeleton, it’s use as a target is more valuable than its recycled value. Not all ships are ended this way, these naval ships are rather small compared to ocean liners and cargo ships that are always broken up to be recycled. 3000 tons vs 30000 tons, not much material in these.
wow..are you sure those two are also operational!
