The Pentagon: the new high-speed ships of the US Navy were vulnerable to high waves

108
High-speed ships that the US Navy ordered from Austal USA cannot withstand the oncoming impacts of high waves, reports RIA News a statement by the head of the Pentagon's operational verification department, Michael Gilmore, published on the Bloomberg website.




“Expeditionary Fast Transport (EPF) Expeditionary Catamaran ships are designed to carry approximately 545 tons of cargo and 312 personnel to a distance of thousands of kilometers to 2,2 at speeds up to 80 kilometers per hour. They were deployed in Africa and the Middle East, as well as in Singapore. The Navy bought ten ships of this type, each of which costs about 217 million dollars ", - explains Bloomberg.

Five of them are already in operation, and 5 is still under construction.

“When building ships, we had to compromise on the design of the bow, apparently to reduce weight,” Gilmore writes in a letter to the US Congress. “As a result, many ships began to suffer damage to the aluminum hull due to a collision with the waves.”

"However, even with the strengthening of the bow, it can be damaged by a high wave," he said.

According to Gilmore, EPF should not go into the sea during high seas or "walk at low speeds."

The repair of the first ship, received in 2012 g and tested in a rough sea, was spent $ 511 thousand. Repair the next three cost more - more than a million for each ship. The fifth EPF is currently awaiting repair.

Electric generators were also unreliable. “In some cases, their work time was just 208 hours instead of the promised 8369,” Bloomberg notes.

    Why are they needed then? Pass in the national economy - let the tourists ride. Capacity is just right.

        ships began to get damaged aluminum hull


        But this is interesting. Aluminum cladding in sea water is a serious task. How do they solve it? And the boat itself is not bad - in certain areas it is much preferable to hovercraft or vehicle ekranoplanes - it’s simpler, cheaper, and it performs the main tasks.

          About the same as simple vessels with a steel hull: coatings and treads from electrochemical corrosion. In the USSR, there is experience in building ships with aluminum hulls, moreover successful: hydrofoil missiles, small-capacity boats, TsAGI torpedo boats.

          Do not compare them - completely different ships with completely different tasks. This is more of a BDK, but not at all like the Bison. But I agree that the boat itself as a BDK is very good, the catamaran scheme is mainly interesting ...

        Not luggage and tourists, but a battalion with equipment. and even 80 km h in quiet water at such a distance - not bad at all. We have no analogues. the most similar - landing ships on an air cushion or ekranopodana, but this topic is killed. So do not gloat.

          Not bad. 80 km / h 2200 km one way. Let 35 hours move. Che weather forecast will not get for 45 hours, so as not to get into the waves?

          Moreover, the very problem of these waves is in doubt.

          Yes of course. If Bradley burns, then the ships are drowning.

    Destruction in the storm of the ocean linear container ship MOL Comfort (Indian Ocean, 2013 year)
    _______________________
    On November 17, the leader of Baku and the destroyer Destructive were brought in to strengthen the escort of the next allied convoy QP-15. In the conditions of a fierce storm, which reached hurricane force by the morning of November 20 (11 wind score), with frequent snowy charges and zero visibility, the convoy and guard ships lost sight of each other, after which the convoy dispersed.

    The impact of a nine-point wave on the Baku leader caused the deck to bend and cracks appear in it, the sunroofs and covers of the ventilation shafts of boiler rooms were deformed, the hull was broken - all rooms with a new tip on the upper deck according to 25 sp. turned out to be flooded, water flowed through the ventilation shafts to the 2 and 3 boiler rooms, only the main boiler No. 1 remained in operation. The ship’s condition turned out to be critical: the leader took over 1 00 t of sea water, the trim on the nose was increasing, the roll reached 40 °. The crew led a desperate struggle for the survivability of the ship.

      “However, even when the bow is strengthened, it can be damaged by a high wave.” EPFs should not go to sea during heavy waves or “walk at low speeds.”
      The repair of the first ship, received in 2012 g and tested in a rough sea, was spent $ 511 thousand. Repair the next three cost more - more than a million for each ship. The fifth EPF is currently awaiting repair.


      And these are not self-propelled self-propelled guns, but high-tech ships, calculated on a computer. Of course, in any ship, during the most severe storm, it can tear something, but here it is not the strongest in the whole series,
