Chapter 658 New Destroyer

"The standard displacement of the destroyer we are going to build is initially set at 1,400 tons." Charles said: "The full load displacement is about 2,000 tons, which can be changed appropriately depending on the situation."

Tijani took a notebook and wrote while saying: "Why don't we just build a cruiser with a standard displacement of about 4,000 tons? The larger the displacement, the stronger the firepower, Lieutenant General, it is even more cost-effective."

As the "crown prince" of the Brest Shipyard, Tijani knows that tonnage and price are not a simple proportional relationship. Often, the larger the tonnage, the lower the average cost.

"Speed, General." Charles' answer was simple: "Under the same technical and industrial levels, the larger the tonnage, the slower the speed."

"Speed?" Tijani stopped writing, looked up at Charles in confusion: "If we already have planes, I mean, planes with torpedoes, why do we need to emphasize the speed of destroyers?"

Charles asked back: "Does it mean that we don't need speed for tanks on land because we have aircraft to cover us?"

Tijani was stunned for a while, and said unwillingly: "But this seems to be different from tanks. Tanks can be covered by numbers, and there are many ways to avoid them, but there are not many warships, and there is no way to avoid facing aircraft at sea."

Charles continued to ask back: "What if the enemy uses torpedo boats or destroyers, which are small but high-speed ships, to besiege? Do we also choose to use aircraft to mount torpedoes to sink them?"

Tijani was speechless.

Sinking a destroyer may be okay, but torpedo boats are fast and difficult to be hit by torpedoes, and even if they are hit, it is not worth it.

Charles then analyzed:

"Any battle should be a system, General."

"In previous naval battles, the system was torpedo boats, destroyers, cruisers and battleships. They cooperated with each other to form a strong combat capability."

"And the new destroyer we built is not just a destroyer, but it breaks this old system to form a new combat system."

Tijani thought for a while, with uncertainty on his face: "You mean, a new system formed by the cooperation of destroyers and aircraft?"

"Yes." Charles replied: "The two cooperate with each other, rather than restrain each other, which requires both to have self-protection capabilities and will not form a short board and be defeated by the enemy one by one."

Tijani understood: "Aircraft have self-protection capabilities. They can fly out of the enemy's firepower at any time and find the right time to join the battle, but warships are not like this."

Char nodded: "The self-protection ability of warships is also speed."

"You are right." Tijani generously admitted his mistake: "So, the tonnage of warships is determined by the current technical level and the speed of the opponent's warships. The enemy's destroyers are at a speed of about 33 knots, and our destroyers must at least have this speed."

With a speed of 33 knots plus aircraft reconnaissance, battleships with a speed of about 19 knots can be completely ignored. They can never catch up with destroyers.

At the same time, cruisers with a speed of about 29 knots can also be basically ignored.

So on the vast ocean, destroyers only need to face enemy destroyers, or add torpedo boats when entering the enemy's coastal waters.

After understanding this, the next step will be much easier.

"Because our main opponent is the enemy destroyer, the naval guns are still indispensable, and the initial setting is 130MM main guns, four guns."

This is determined by the fact that the firepower of enemy destroyers and dive bombers in this era have not yet developed, and the new destroyer cannot have only one or two naval guns like in modern times.

"In addition, add 2 triple-mounted torpedo tubes."

The torpedo tubes of destroyers in this period are mostly twin-mounted. The purpose of Charles using triple-mounted is to increase the number of torpedoes it can launch at one time, so that the strike capability of the new torpedo can be better exerted.

"2 depth charge rails, 22 bombs in reserve."

Charles deliberately weakened the anti-submarine needs of the destroyer.

The reason is that the main opponent of the French fleet is not the German Navy but the British Royal Navy.

On the other hand, Charles's new destroyer is used for mobile warfare at sea, and it uses a high-speed maneuver at a speed of 33 knots instead of escort.

The submarines of World War I had more than ten knots on the surface and only about eight to ten knots underwater, which could not pose a threat to this warship at all.

Tijani wrote them down one by one. Although he was a little confused about the anti-submarine aspect, he didn't ask too much.

After thinking for a while, he asked a question: "I heard that our new warship is mainly used for air defense, but so far, I haven't seen any anti-aircraft firepower."

Charle took out a drawing from the drawer and handed it to Tijani: "The anti-aircraft firepower uses this machine gun, 20MM caliber."

"20MM caliber?" Tijani asked in confusion: "The German Becker gun?"

But after taking Charles's drawing, he found that the machine gun on the drawing was somewhat different from the Becker gun. The general structure was the same, but the barrel was longer and thinner.

No mistake, one sentence, one content, one book, one bar, one 6, one 9, one book, one bar, take a look!

(The above picture shows the prototype of the Oerlikon cannon, invented by the German Becker, so it is called the Becker cannon. The cannon was originally used by the Germans on airplanes, but was soon shot down and captured by the Allies. Its characteristic is that it pioneered a unique pre-firing recoil method, which reduced the recoil force, so it was widely used in anti-aircraft cannons and aircraft cannons)

(The above picture shows the Oerlikon cannon used in large quantities on warships)

Charles only showed the blueprint to Tijani and took it back, handing over a data file instead.

"I am responsible for the production of the machine gun." Charles said, "You only need to know these data and reserve gun positions for its side."

It is not a secret that this machine gun is used for air defense, but Charles's improved version of the Oerlikon 20MM machine gun is a secret. It has a higher rate of fire and initial velocity than the original Becker, and its performance has been significantly improved. This is not something that can be easily disclosed.

Charles plans to hand over this gun to the artillery factory in Darvaz for production.

Charles believes that things related to the balance of one's own equipment should be kept sufficiently cautious.

For example, this Oerlikon machine gun, nearly 30% of the planes in World War II were shot down by it.

In addition, it can also be used as an aircraft cannon.

One day, as long as it is installed on an airplane to strafe a tank, it can easily penetrate the top armor of the tank and become a ground attack aircraft.

Tijani certainly understood the pros and cons of this, and he nodded to show his understanding: "I understand, Lieutenant General. If it were me, I would also do everything I could to keep it secret. After all, you are inventing equipment to counter your own equipment."

Then he laughed: "This must be very tiring, I mean, you become your own opponent!"

Char sighed in his heart.

This situation is bound to occur when the number of invented equipment reaches a certain level.

Now we can only hope that the enemy will not imitate it so quickly and "feed back" to us!
