Were battleships useless in ww2?
Yes there were. Therefore they were not obsolete. Planes were faster than battleships and just a few planes could cripple or even sink a battleship or battle cruiser. That’s maybe half a dozen pilots sinking a ship with a crew of over 1,000.
How big were ww2 submarines?
Their massive size and displacement — about 200 feet to 300 feet long and over 2,000 tons submerged — allowed them to sail much farther than smaller submarines and without assistance.
Where is Surcouf located?
Surcouf was named after the French privateer Robert Surcouf. She was the largest submarine built until surpassed by the first Japanese I-400-class submarine in 1944….Second World War.
| Date | 3 July 1940 |

Do modern submarines have guns?
However, guided missiles give submarines a a greater capability to attack surface targets, on the sea or land, than a gun would and the submarine does not have to surface to employ the missiles. There is no deck gun that I know about that could be effectively fired while submerged.
What is the difference between a cruiser and a battleship?
The key difference is that while battleships had thick armor plating that could block projectiles as large as the ones they fired, battlecruisers sacrificed protection for speed. Hence the term ‘battlecruiser’, a ship with the firepower of a battleship but the speed and protection of a cruiser.
Why do we not build battleships anymore?
They are not suited to the objectives navies want to achieve and they are incredibly expensive. A battleship’s guns have very limited accurate range of around 20,000 yds, modern anti-ship missiles have ranges of tens or hundreds of miles and can be carried by ships, aircraft or fired from land.
How did submarines work in WW2?
World War II submarines were basically surface ships that could travel underwater for a limited time. Diesel engines gave them high surface speed and long range, but speed and range were severely reduced underwater, where they relied on electric motors powered by relatively short-lived storage batteries.
How did submarines navigate in WW2?
In the days prior to SONAR, Subs navigated the same way every other ship did. They took position fixes when they could (triangulated visual fixes, Celestial fixes, et al, and used dead reckoning in between, taking into account currents and the winds, because Subs of that era spent 90\% of their time on the surface.
What happens when submarine implodes?
Submarines don’t actually implode very often, so we don’t have direct evidence. But, when they do the pressure hull fails violently and catastrophically. Most likely death is due to traumatic injury. They’re probably crushed by the hull, internal equipment or the force of seawater coming into the breached hull.
What is the largest submarine?
Typhoon-class submarine
Submarine/Biggest
The worlds largest submarines are the Russian 941 Akula (designated ‘Typhoon’ by NATO) class. The launch of the first at the secret covered shipyard at Severodvinsk in the White Sea was announced by NATO on 23 Sep 1980.
When did submarines stop having deck guns?
The end of the deck guns After the massive anti-submarine build-up by the allies in 1942 and 1943 the deck guns were removed from almost all the boats in 1943 and 1944.
Do submarines use lasers?
“A laser could be mounted to the submarine outside the pressure hull,” Clark says. “For example, it could be in the sail, which is normally flooded when the submarine is submerged. Mounting in the sail could allow the laser to be used above the water to dazzle optical sensors or damage manned or unmanned aircraft.”
What was the role of the cruiser submarine in WW1?
Their role was analogous to surface cruisers, cruising distant waters, commerce raiding, and scouting for the battle fleet. Cruiser submarines were successful for a brief period of World War I, but were less successful than smaller submarines during World War II.
What are the disadvantages of a large submarine?
Large submarines remained vulnerable to damage from defensively equipped merchant ships (DEMS), were slow to dive if found by aircraft, offered a large sonar echo surface, and were less able to defensively maneuver during depth charge attacks. Surcouf had the largest guns of any cruiser submarine.
What is a long-range submarine called?
Long-range submarines with less impressive deck guns, including Type IXD2 U-boats and United States Navy fleet submarines, evolved through the Second World War; and may be identified as cruiser submarines in comparison to submarines designed for shorter patrols over lesser distances.
Why did Germany use U 139 submarines in WW1?
Three German Type U 139 submarines and seven former merchant submarines, each armed with two 15-centimetre (5.9 in) guns, patrolled areas distant from their North Sea bases to sink Allied merchant shipping as part of an effort to end World War I by starving the United Kingdom of Great Britain and Ireland.
