Although the second-generation submarine of the Tang Empire was successfully developed, and its performance was ahead of the standard of a whole generation of submarines in various countries, the cost was also quite high, and the construction of 1 Carp-class submarine was equivalent to the construction of 3 V-4 submarines.

The Tang Army built 20 carp-class submarines in 18 months, and although this speed is already very fast, the war situation seems to be progressing faster.

The submarines of the Tang Army were mainly used against the British Navy, because among the hostile countries of the Tang Empire at the moment, the British Navy was the most powerful.

However, Britain only looks strong, and it has long lost its pre-war prestige. With the launch of Operation Sea Lion by the Germans against the British, the German submarine wolf pack tactics had exhausted the British navy, and the British industry, which relied on maritime trade and energy supplies, was severely damaged, and the German army seized air supremacy and continued to bomb the British mainland, so that most of the factories in the tiny British Isles were blown up.

Although American merchant ships continued to send supplies to the British, the scale was too small to quench the thirst of the near water, and the British were on the verge of starvation and mental breakdown, which indirectly affected the British army's will to fight.

On March 2, 1939, Germany and the Tang Empire reached an agreement on a joint attack on the British mainland, and the Atlantic Fleet of the Tang Navy was responsible for containing the main force of the British Royal Navy and covering the transport ships to send the German Army to the British coast. The Germans sent eight panzer divisions and ten infantry divisions to attack the British mainland.

The landing site of the Don and German armies was finally chosen at Dover, because it was the narrowest part of the English Channel, and the Germans were afraid of the sea. I am worried that it is too risky to choose other places by sea.

However, the British army was not stupid, and Dover was the closest to France. London was also over there, and once Dover fell, London would be an undefended city. Therefore, the British army also placed the main force on the front line of Dover, with a strength of up to 200,000.

The Tang Empire suggested that the German army choose to land in Britain elsewhere, but the German army thought very highly of itself and did not take the so-called main force of the British army in its eyes at all. What's more, under the premise of seizing air supremacy, the German army's steel torrent was enough to sweep away the main force of the 200,000 British army in Dover.

However, at the suggestion of the General Staff of the Tang Empire. The Germans still listened to the advice of the Tang army, that is, to attack the east and the west.

The Tang Army suggested that a heavy army group be deployed on the front line of Rouen, and that it should be made to directly attack Jiashi, the British naval base in Portsmouth, and end up the nest of the British Navy. will force the British to surrender. The British apparently knew this. Therefore, the main forces of the navy must be mobilized to blockade the place, so that the German army will not succeed in crossing.

On March 2, the main force of the Atlantic Fleet of the Tang Imperial Navy assembled in Tulaville, France, and the German army sent many troop carriers to anchor there to cooperate with the Tang Army to make the illusion of launching a landing in Britain there.

The British panicked, believing that the defense of the Dover line was sufficient, but the defensive forces in the direction of Portsmouth were too weak, so the main forces of the British navy quickly gathered in the southern seas. Confront the navy of the Tang Empire to prevent the other side from breaking through the naval blockade.

The British Navy has six main aircraft carriers. There are two more main aircraft carriers than the Tang Army's Atlantic Fleet, but the British Navy's carrier-based aircraft performance is not enough to compete with the Tang Army, so this is also the main reason why the British Navy has not dared to engage the Tang Navy head-on.

Now that it is forced to be helpless, the British Navy has no choice but to fight hard.

From 7 o'clock in the morning, without waiting for the Datang Navy to attack, the British Navy rushed to attack to cover up the fear in their hearts, and they dispatched 100 Spitfire carrier-based fighters and 80 Swordfish attack planes to strike first and win a good start.

Datang's only special service ship carrying a radar system is in the Atlantic Fleet, which was also sent just in case.

As a result, as soon as the British naval aviation was dispatched, it was quickly detected by the Tang army, which immediately prepared for battle, and the whole fleet entered the state of air defense operations, and at the same time dispatched 300 Raptor heavy carrier-based fighters to take off and quietly lay in ambush above the nearby clouds, waiting for the arrival of British naval aviation.

Just as the British Air Force relied on ground-based radar stations to ambush the Luftwaffe at the beginning, they did not know that the Tang Empire also had advanced radar jishu, which was destined to suffer a big loss.

When the British naval aviation swore to the halfway point, the Tang fighters suddenly swooped down from the clouds.

It was a massacre, the Tang Army's Raptor heavy ships were extremely fast and had super firepower, and the British Army's slowest Swordfish attack aircraft were the first to be damaged, and the British pilots hung up before they even saw the shells fired from that side, and one after another fell in flames.

Compared to the Swordfish attack aircraft, the situation of the British Spitfire is better, this is a streamlined foreign trade version of the Raptor fighter, except that the armor is thinner, and the speed is not weaker than the opponent. It is equipped with a point 50 heavy machine gun, although it is still a little different from the 20mm cannon of the Raptor, but compared with the Japanese Type 96, the British army's airborne firepower is much stronger.

The quality of the British pilots was also much stronger than that of the Japanese army, after all, the British had experienced the first Shijie battle, and many British pilots were still able to fight back when the Tang Army planes suddenly killed.

However, the Tang Army's fighter jets were too numerous, and they were in the innate advantage of sneak attacks, one hundred British Spitfires were attacked at the beginning and more than 30 fell, and the remaining less than 70 Spitfires faced the siege of 300 Birds of Prey, and they were defeated in less than 20 minutes, except for the twelve Spitfires that fled when they saw that the situation was not good at the beginning, the rest were all shot down, and the Tang Army only paid the small price of six Raptors being shot down to win the first battle.

After the first 300 Raptors took off, 200 Hellfire heavy carrier-based bombers also took off, and they went to the position of the British Navy's aircraft carrier battle group to sink all the British aircraft carriers.

However, the defense of the British Navy is still very strong, mainly because of the large number of warships of the British Navy, the dense anti-aircraft fire network on the entire sea, plus the escort of six British main aircraft carriers and a group of fighters, the bomber group of the Tang Army failed to achieve the set tactical objectives, but it also gave the British Army a heavy lesson, two heavy cruisers and six destroyers were sunk by the Tang Army.

In the first round, the British Navy was defeated, and the Tang Army was originally afraid, and the negative emotions of the defeat in the battle at this time suddenly affected the entire Royal Navy. Seeing that the first battle had been lost, and that the British army had lost more than 200 carrier-based aircraft, the British high command did not dare to fight again, and they also counted on the British naval aviation to support the ground defense at a critical moment, after all, it was the only Liliang of the British Air Force.

The main force of the British Navy withdrew to the Portsmouth base, relying on coastal artillery fire and air defense Liliang to stop the attack of the Tang Navy, but they did not know that the Tang Navy had no intention of attacking at all, they originally only wanted to contain the main force of the British Navy, but now they are besieging the other side in the Portsmouth base, which makes the Tang Empire very happy, because this is equivalent to the British Navy directly giving the sea control to the Tang Dynasty.

The Tang Navy quickly laid mines on the periphery of Portsmouth, blocking the main force of the British Navy in the base and unable to come out, and the Tang Army would send a group of fighters to cover the bombers to attack Portsmouth every day to attract the attention of the British army.
