One of the reasons why Shiina Taro thinks this is that the Japanese submarine forces are basically not working together...... The Japanese army's coordinated operations have always been a basic weakness, and even more so in terms of submarines, and it can even be said that the Japanese army does not know how to use submarines at all, for example, they have always used submarines to attack destroyers and aircraft carriers, instead of choosing enemy transport ships that are easier to attack and safer.

In this battle, Shiina Taro asked planes and submarines to work together...... For his part, Shiina Taro does not require the submarine and the aircraft to cooperate closely, he only wants the submarine and the aircraft group to be able to launch an attack on the Chinese ship group at about the same time.

As a result, Chinese warships will face the dilemma of taking care of one or the other...... They have only twelve destroyers, and these destroyers will inevitably ignore anti-submarine if they want air defense, and if they want anti-submarine, they will inevitably ignore air defense.

At this point, Shiina Taro pinned his hopes on the submarine, because the enemy had anti-air and anti-sea radars, which could easily detect the Japanese aircraft group, while the submarine could potentially escape the enemy's eyes.

This can also be seen in the contradictory character of the Japanese, or it can also be said that Shiina Taro is not sure whether the battle should focus on fighters or submarines, and if there is a focus, then it is okay to decide to cover the submarine with fighters, or use submarines to cover fighters...... But Taro Shiina is on both sides, hoping to reach both at the same time and attack the enemy at the same time.

This tactical idea is very good, and if it can be achieved, it will indeed cause great trouble for the Chinese army.

But Shiina Taro completely failed to take into account the technical feasibility of this tactic for Japanese submarines......

The problem is not Japanese submarines, which can be lurking in the water for long periods of time and are difficult to detect, and can even lurk near the target waters in advance to wait for orders. So it was perfectly feasible to do what Shiina had envisioned and attack the target at the same time.

The problem lies in the "anti-torpedoes" carried by the submarines.

The "Huitian Torpedo" thing is to bring people, that is, it has to be operated by a person...... Although this can greatly improve its hit accuracy, it can also bring a series of troubles.

For example, the diameter of the "Huitian torpedo" reached one meter...... Not a meter, the total length is almost fifteen meters.

Without this width and length, it would not have been possible to fit a single person, the necessary control system, and three times more explosives than an ordinary torpedo (note: the Huitian torpedo charge is 1550 kg).

The consequence of this is that this torpedo cannot be carried in the launch tube of a submarine like a normal torpedo, but is fixed to the deck of the submarine and is released when it is to be launched.

This may seem like a trivial matter...... Isn't it just that the deck of the submarine carries several torpedoes with a diameter of one meter? It doesn't have much of an impact in the potential water!

But in fact, this has a big impact, and the most direct impact is to make the already slow underwater speed even slower, and the depth of the dive is also greatly affected...... "Huitian torpedo" can not stand too much water pressure.

What is even more serious is that the "Huitian torpedo" is to bring people, and there is no oxygen system in the "Huitian torpedo", and there is no pipeline connected to the submarine in the "Huitian torpedo".

For many reasons, the "Huitian Torpedo" must be prepared for attack before attacking the submarine.

The "offensive preparation" here means that the operator must enter the "anti-torpedo" and carry an oxygen cylinder to provide breathing for the operator.

In other words, the Japanese submarine had to have an action, that is, to float when it was very close to the target, and then let the operator climb from the submarine into the "Huitian torpedo" before diving to attack the target.

This distance is usually considered to be six kilometers, because the underwater speed of the Japanese I-type submarine is only seven to eight knots, and it takes about an hour to sail for six kilometers.

This action is obviously very dangerous...... In particular, in order to achieve the goal of Taro Shiina launching an attack on the Chinese fleet at the same time, the three submarines of the Japanese "Chiba" special attack group had to be "ready for attack" at about the same time, that is, they surfaced almost at the same time.

The sirens immediately sounded in the Chinese ship group.

Zhang Chi, who was resting in the command cabin of the aircraft carrier, jumped up from the bed and asked, "What's the situation?!" ”

"Master!" Staff Officer Liang replied loudly: "Enemy submarines have been discovered, three ...... Five kilometers, five and a half kilometers, four kilometers away! ”

Hearing this, Zhang Chi couldn't help but gasp, and three submarines appeared at this time.

But think again...... No, isn't it okay for these three submarines to approach quietly and then launch a sneak attack? Why float at the same time at such a close distance? And it's still daylight?!

Then he thought about it again, and Zhang Chi's face turned pale immediately...... The devil must have dispatched a "Huitian torpedo".

At that moment, Zhang Chi no longer hesitated, and ordered: "Act quickly, immediately send fighters and destroyers to sink it!" ”

"Yes!" Staff Officer Liang answered, and immediately assigned one destroyer and two fighters in each direction.

Zhang Chi did not dare to send too many destroyers and fighters out, which is also common sense in naval warfare...... If too many forces are allocated, the result will be a reduction in the protective strength of the aircraft carrier, which is the most deadly.

The speed of the fighters was the fastest, because there were already several fighters patrolling over the sea area, and as soon as they received the order, they flew towards the designated position, and then soon discovered the submarine that was still making preparations, that is, arranging personnel to climb into the "Huitian torpedo."

Of course, the pilots will not be polite to the devils, and they will shoot rows of bullets at the submarine with a single dive...... Submarines can be said to have little protective armor, and once a bullet or cannon makes a hole in the place, it will be very dangerous when diving.

As a result, the three submarines of the "Chigusa" special attack group lost two of them before they could launch an attack, one was bombed and sunk on the spot by a bomber assigned to a reconnaissance mission, and the other was damaged and could not be sunk, and was also sunk by the destroyer that arrived later.

The only one, the "Yi-44", successfully escaped the round-up of the Chinese army's fighters and destroyers...... The captain of this submarine was Osa Eguchi, and he was a smart man, knowing that once the submarine went up, it would definitely expose the target and attract enemy planes, so it was the first to float and only two operators were arranged to board the "Huitian torpedo...... Eguchi Daisa had calculated the time in advance, and even if it was one second longer, the "I-44" would not be able to successfully dive.
