Before Li Haichen and the others could be happy, a violent humming sound suddenly sounded from the clouds above the fleet, as if there was a large number of planes.

Li Haichen received a telegram from the Tang Emperor's [***] Command in advance informing him that a naval and air force military exercise codenamed Sword Unsheath would be held in a certain sea area in the Pacific Ocean near the mainland of the Tang Empire.

The previous submarine sneak attack was just a small prelude.

Li Haichen understood that it should be the bomber group formation of the Royal Air Force of the Tang Empire.

Li Haichen did not know how many bombers participated in the exercise, but he could tell from the sound that there were at least two hundred. For the purpose of the exercise, Li Haichen did not tell anyone other than Instructor Stephen, so as to test the actual combat reaction ability of the officers and men of the whole fleet.

"Battle Alert!"

"Yes! Battle Alert! ”

At the sound of the order, the light cruiser Leander immediately sounded the air defense alarm, followed by the sirens on the other five battleships.

In a moment, the siren sounded in the sky within a radius of 100 kilometers.

"Hurry up!"

"Hurry up!"

Officers at all levels held stopwatches in their hands and shouted at the sailors, they had only one counterinsurgency criterion, that is, to get all the sailors into their respective combat positions in the shortest possible time.

In terms of naval operations and anti-submarine warfare, the more than 2,000 officers and men of the First Fleet of the Royal Navy of the Tang Empire performed very well. However, because the British Royal Navy does not attach importance to ship-to-air combat, there is only one ship-to-air shooting course of less than half an hour in the tutorial at the Manchester Sea Training Center. In joint exercises with the fleets of the Royal Navy, there were also no air defense exercises, which led to a lack of awareness and training in air defense.

Three minutes and forty-three seconds!

When the gunner of the last anti-aircraft rapid-fire gun was ready, Li Haichen jammed the timer and couldn't help frowning.

This air defense preparation time seems to be nearly half a minute faster than the preparation time for sea operations and anti-submarine warfare, but Li Haichen knows very well that this time is enough for the enemy's planes to get close to the fleet and launch an attack.

Sure enough, the first echelon of the 'enemy' bomber group had already rushed down from the clouds.

"Air combat!"

"Fire!"

At the sound of the order, the ship's anti-aircraft artillery and anti-aircraft machine guns opened heavy fire.

Although a rubber warhead with a one-third charge is used, it still has considerable kinetic lethality at a certain altitude, and this is unavoidable, so the 'casualty quota' in the exercise is also within the allowable range.

Through the telescope, Li Haichen observed that the trajectory of his own anti-aircraft fire deviated far from the enemy planes, and basically chased the tail of the enemy planes and opened fire.

This is because the speed of the simulated airplanes they usually practice is very slow, and the anti-aircraft anti-aircraft machine guns that do not have any improvement still use the crosshairs of ships and infantry, and when faced with real planes that are ten times faster, they cannot estimate the accurate amount of advance at the first time, and naturally they will not be able to hit the other side.

The first echelon of the attacking fleet consisted of 50 torpedo-mounted Seal torpedo reconnaissance aircraft. This kind of torpedo reconnaissance aircraft was introduced from the United Kingdom, and it was a biplane fixed landing gear reconnaissance torpedo aircraft tailored for British aircraft carriers by the British Beremon Company. As the name suggests, it is to follow the aircraft carrier to the sea in peacetime, use it as a reconnaissance aircraft, and if necessary, it can install a torpedo to attack the ship. Because the role of aircraft carriers in the British Navy is only to provide maritime reconnaissance for the main force of the British Royal Navy fleet, this kind of reconnaissance torpedo machine appeared.

Since Zhang Meng really couldn't find a bomber that was easier for newcomers to get started with than the seal torpedo reconnaissance plane, and the new torpedo attack plane designed by his Raptor Airlines was still being tested, he could only use the seal torpedo reconnaissance plane for training and use.

Fortunately, this low-speed two-seater propeller aircraft is easy to operate, so it is easy for novice pilots of the Royal Air Force of the Tang Empire to learn to fly, which makes the Royal Air Force of the Tang Empire quickly form combat effectiveness.

Under the leadership of Lieutenant Colonel Lei Zhen, the leader of the group, fifty seal torpedo reconnaissance planes quickly descended to the sea level and flew towards the target fleet at a speed of 260 kilometers per hour.

Since the pilots of the Royal Air Force of the Tang Empire have not experienced real aviation school learning, they all started from a blank sheet of paper, fortunately, they flew propeller-type low-speed aircraft in the twenties, and the technical requirements were not very high, plus Raptor Airlines sent a group of professional pilots as air trainers, these air trainers are aerobatic pilots who test fly new aircraft, so under their training, the pilots of the Royal Air Force of the Tang Empire have grown up rapidly. Even a group of naturally gifted pilots represented by Lei Zhen adapted the fastest and stood out as the backbone.

However, even if they have developed their aerobatic skills under the guidance of aerobatic instructors, at the level of war, those aerobatic instructors are only test pilots and do not understand strategy and tactics, so they can only rely on the classic air combat subjects during World War I to teach them step by step.

Due to the lack of classic examples of bomber groups attacking the fleet during World War I, Lei Zhen could only be influenced by the operational thinking of the US naval aviation and launched an attack in the traditional way of concentrating all the torpedoes on one side of the fleet.

When the mechanical altimeter was displayed at an altitude of 30 meters above sea level, 50 torpedo attack planes opened the padlocks under their bellies and dropped 533-mm torpedoes weighing 800 kilograms each.

The torpedo plunged headlong into the sea, and it was customary to make it plunge more than ten meters below the surface of the sea before rising to the surface with the help of buoyancy, and with the help of a gas engine, it shot at the battleship at a speed of 80 knots.

"Torpedo spotted!"

"On the port side!"

"Multiple torpedoes are approaching!"

"Left full rudder full speed evasion!"

"Implement sea shooting to intercept torpedoes!"

……

The commanders of the ships gave orders in an orderly manner, and for a light cruiser with a combat speed of more than 30 knots, there was no problem in dodging three or four torpedo attacks. However, the opponent dropped as many as 50 torpedoes at a time, and each battleship faced an average of nearly 6 torpedoes.

Ten seconds later, three battleships, the Amphion, Alisiusa, and Falca, were torpedoed.

The officers and men on these three battleships did not know that it was an exercise, and thought that they would definitely die at this moment, and the moment the torpedo hit the battleship, they all closed their eyes in unison.
