If you want to say, the intelligence problems of the Nuland Navy are even more acute.

The reason is also very simple, the Nuland Federation has not been able to establish a perfect, effective and in-depth spy network in the Liangxia Empire.

This is understandable, after all, the differences between races are too great.

Of course, the Nuland intelligence agency has been working on it.

Before the outbreak of the war, the Nuland intelligence agency recruited a large number of descendants of immigrants from the East, the vast majority of whom were expatriates from the southern Pearl Kingdom.

After spending huge resources to train these personnel, they will try their best to send them to the Liangxia Empire.

However, soon after the outbreak of the Great War, the intelligence network composed of these spies was eradicated by the intelligence and security agencies of the Liangxia Empire in one fell swoop, and more than ninety percent of the spies disappeared, and the intelligence network that the Nuland intelligence agencies had spent decades building up was wiped out.

It wasn't until the official entry into the war, that is, after the defeat of the Narrow Empire, that the Nuland intelligence agencies figured out what the problem was.

A qualified spy must not only have a similar appearance, but also be well-versed in the culture and customs of the country where he is lurking, so that he can dress up as a local.

In this regard, the narrow intelligence agencies have done a better job.

In fact, it was only after the defeat of the Narrow Imperial State that a large number of intelligence personnel were exiled to the Nuland Federation, and the Nuland intelligence agency obtained more reliable intelligence clues.

It's just that it's far from efficient.

No matter how much the narrow-minded intelligence agents boast, at least so far, there hasn't been much decisive, high-value intelligence for the Nuland Federation.

On the contrary, a lot of money has been spent.

It is precisely for this reason that the Nuland Navy is also trying to improve its intelligence system, or to seek and build the means to obtain intelligence.

In the Navy, submarines are the main force in carrying out strategic reconnaissance missions.

Relatively speaking, Spu preferred to trust the submarines of the Navy.

Although the main task of the Nuland Navy is anti-submarine and escort in the North Sunset, in the Guia Ocean, the Nuland Navy plays another role.

When it comes to breaking diplomatic operations, the Nuland Navy is very similar to the Manchurian Navy.

Long before the outbreak of the Great War, the Nuland Navy recognized the great value of submarines in the Guia theater and attached great importance to ocean-going submarines.

Crucially, the Nuland Federation was the victor in the last war.

In the development of submarines, except for the "Hwaseong Treaty" and the "Luntai Treaty", they will not be severely restricted as in the Hindman Empire.

Geographically, because the western part of the Guia Ocean is densely populated with islands and has dozens of major shipping routes, while in the eastern part there are almost no islands and there are only a few shipping routes, it is more suitable for the Nuland Navy, which is located on the eastern shore of the Guia Ocean, to send ocean-going submarines to the western Guia Ocean to carry out the task of breaking diplomatic relations.

It is precisely because before the outbreak of the Great War that the Nuland Navy had the largest submarine fleet in the Guia Ocean, and almost all of its ocean-going submarines were deployed in the Guia Ocean.

According to the strategic vision of the Nuland Navy, these submarines are the first line of defense.

After the outbreak of the war, the Nuland Navy immediately increased the scale of submarine construction, and broke peacetime regulations, allowing many small shipyards to directly build ocean-going submarines for the Navy without paying patent fees, taking the design drawings of large shipyards.

Now the Nuland Navy has more than 100 ocean-going submarines.

The Manman Navy, which has always regarded submarines as its main force, has less than 100 ocean-going submarines!

The point is, these submarines are all in the Guina, and most of them are on the Guina side.

Although the number one task of the submarine is to break diplomatic relations, mainly to go to the West and East to look at the ocean, and the Yanhai Sea to find and attack the transport ships of the Liang Xia Empire, and if there is a chance, to sneak attack large warships without anti-submarine capabilities, but all submarines must take into account the reconnaissance mission.

According to the order given by the command of the Guia Fleet, after discovering the enemy's capital ships, especially aircraft carriers, the first thing to do was not to launch torpedoes, but to send telegrams. If the enemy's fleet is encountered, then it must be reported to the fleet command after determining the size of the fleet.

At any given time, dozens of submarines were operating in the Guia.

When arranging the mission, the commander of the submarine force will make it clear that during the sortie and return phase, he will have to make a detour to the forward base of the Liangxia Navy, that is, to go around the main islands of the Volcanic Islands and the North Malaysia Islands, so as not to catch the opportunity to sink the fleet's aircraft carriers.

Usually, when planning a mission, the captain will reserve the fuel and supplies needed for the circumnavigation.

In any case, it was definitely a great honor for the submarine commander to be able to sink the fleet aircraft carrier with a torpedo.

For an ocean-going submarine with a cruising range of more than 15,000 nautical miles and a self-sustaining power of at least 90 days, it is not a big deal to run a few hundred nautical miles more on the way to attack and return.

Of course, in order to encourage submarine captains to carry out reconnaissance missions, Nyze introduced a reward system.

After sinking a 10,000-ton warship, all officers and men of the ship will be given three months of paid leave, and they will also be sent back to the mainland by special plane to reunite with their families. If you sink 1 battleship, you get half a year's paid vacation and an additional reward. If an aircraft carrier is sunk, even if it is a small aircraft carrier, up to half of the officers and men can be allowed to retire early in the form of full subsidies, starting from the captain down.

Of course, so far, not a single submarine officer or crew has been given the opportunity to retire early, and none of them have even received a half-year vacation.

It is not that the officers and men of the submarine are not working hard enough, nor is it bad luck, but that the Liangxia Navy attaches great importance to anti-submarine.

In a sense, this is related to the lack of effective anti-submarine means in the Liangxia Navy.

In order to avoid being plotted by submarines, the Liangxia Navy can be said to do everything. The most typical is to deploy a sufficient number of long-range patrol planes in all ports and anchorages, and also let patrol planes be dispatched without abbreviation, setting up anti-submarine patrol areas of hundreds of kilometers.

Obviously, no submarine is capable of diving hundreds of kilometers under water.

As for sailing on the sea at night, it is limited by the speed of the voyage and cannot go that far.

So far, half of the dozens of submarines lost by the Nuland Navy in the Guia Ocean have been discovered and sunk on the way to the Liangxia Military Port.

It's just that, for Spu, he definitely prefers to believe the reconnaissance report of the submarine.

Among other things, most of the reconnaissance information provided by submarines so far has been accurate and far more credible than the intelligence provided by spies.

Now, Spu: They are waiting for the submarine's reconnaissance report.

The reason is also very simple.

When Sp returned to Treasure Harbor, he not only raised the alarm, but also persuaded Nyze, in his capacity as commander-in-chief of the fleet, to give an order to all submarines operating in the Guia Ocean, so that the nearest, or more accurate, submarines with enough remaining fuel and supplies rushed to the Volcanic Islands, closely monitored the three anchorages, and reported as soon as they made a discovery.

At that time, 11 submarines replied to the telegram, indicating that they were on their way to the volcanic islands.

In addition, there must have been a number of submarines in the return phase that had also received the telegram, and perhaps some of them would have turned to the Volcanic Islands.

All in all, there are more than a dozen submarines in the vicinity of the volcanic archipelago.

As expected, those submarines are almost already in place.

If the Liangxia fleet has already been dispatched, then the report of the submarine will be received soon!
