The patrol ships in the Datang Navy are positioned to share the pressure of the capital ships, and they do some miscellaneous work, so although the tonnage of this kind of warship is not small, the early patrol ships have about 150 tons, and the patrol ships that began to be built in the later period basically have a standard displacement of 180 tons.

This tonnage is actually not small, you must know that most of the ships currently running the East Asian route, a considerable number of ocean-going merchant ships are only one or two hundred tons.

But as a warship, this tonnage is obviously on the small side.

At present, the Datang Navy's standard positioning of capital ships is that battleships start at 1,000 tons, but in fact, even the first battleship has a standard displacement of 1,300 tons.

The standard for cruisers is more than 500 tons, the first generation of cruisers, that is, the Lianzhou-class cruisers, also have 550 tons, and the first generation cruisers that are now under construction have soared to 800 tons.

Even for frigates, the first generation of frigates was three hundred and fifty tons, but now it has risen to four hundred and fifty tons.

That is to say, at present, the lowest tonnage of the main ships of the Navy is 350 tons, and the number under construction is 450 tons.

In comparison, the second-generation patrol ship, which is a full circle smaller, is only 180 tons.

The combat effectiveness of the warships in these years was basically equal in size, because the larger the tonnage, the more guns could be loaded.

A battleship can carry more than 60 guns, and all of them are large-caliber naval guns, while a 180-ton patrol ship can only carry more than 10 guns, and it is mainly small and medium-caliber artillery, and the firepower is not at the same level at all.

However, the weakness of the patrol ship is relative to the capital ship of the Datang Navy, and if it is against the warships of other indigenous countries, then whether it is weak or not has to be said separately.

More than a dozen artillery pieces are not much, but less is not less.

In addition, this type of ship is small, has a large sail area, and is equipped with oars for offshore inland river operations, so it is quite flexible.

Therefore, when these two patrol ships enter the Han River, they can not only provide cover for the two bulky temporary conversion fire support ships, but also exert their powerful firepower to support the land.

Two converted merchant ships and two patrol ships constituted a powerful fire support for the landing force to enter the Han River, after all, these four ships were loaded with nearly 100 guns.

This firepower is actually stronger than the firepower of an entire division of the 15th Infantry Division!

The total number of landing troops that entered Seoul after the landing was only 3,000, but these 3,000 people were supported by nearly 100 naval guns.

Well, the premise is to fight on the banks of the Han River, and if it is out of the range of the shore, then you can only rely on the marines themselves.

But it doesn't matter, in addition to the marines of the Navy itself, there is also a mixed battalion of the Guards in the landing force, and the total strength is not much, only a thousand people.

However, in addition to an infantry battalion, this Guards battalion also has an artillery team and other baggage troops, and the Guards have never sent infantry or cavalry or artillery separately when they go out to fight, and they are often temporarily integrated to send a mixed force.

If the scale is larger, it will be a mixed brigade, the medium one will be a mixed regiment, and the smaller one will be a mixed battalion.

It is worth mentioning that although the artillery team in the mixed battalion of this Guards Army carried over was no different from the field guns of other army and marines, they were all ordinary five-pound field guns, but the shells they used were different.

This is because the shells they use are not ordinary solid shells or scattered shells, but grenades that have not yet been officially equipped in the army and navy.

The Tang Dynasty was developed before the grenade, but because the technical details were not perfect enough, and the construction of the production line also took time, in addition, during the many live fire tests, some small problems were also exposed, so for a long time, the grenades were in the stage of technical perfection, and the production was only produced in small batches, which were basically taken away by the Guards.

The army and navy, except for a small number of tests, are not massively equipped!

But today, the Guards artillery team, which came to the Goryeo Peninsula, used grenades.

Although there were not many, they only had a few artillery pieces in total, and the number of grenades they carried was only enough for their own use, but when attacking Seoul, they still played a huge role.

When they shelled the natives of Seoul, the scene almost made the artillery of the Marine Corps next door look at it!

Although their navy is called a turtle by the officers and men of the army, the navy is actually well-informed, and they know and use this grenade, and it is a big guy like 48 catties and 24 catties.

But it was precisely because of the use of these artillery pieces that when they saw the Guards firing grenades with only five pounds of field guns, their eyes were wide open, for fear of missing any detail.

Many of them know that the Navy is already testing grenades, and it is estimated that they will be equipped in large quantities in the near future, but to be honest, this is just a rumor, and they have never seen a grenade that can really be fired from a long-barreled artillery.

When they see it, it's a curiosity!

These grenades can be fired with long-barreled guns, and this is almost the same as ordinary solid shells, which is much easier to operate than short-barreled heavy howitzers, and the rate of fire is also higher.

And more importantly, the accuracy of the fuse is much better.

After the shells were fired, although it was inevitable that some shells would explode in mid-air, most of them were still within an acceptable range, and there was no incident where the shells exploded as soon as they came out of the breech.

After seeing the artillery of the Guards shelling with grenades, they didn't even bother to look at the death and injury of the natives, anyway, the natives of Seoul had collapsed, and in the face of the powerful landing force and naval artillery fire, they basically couldn't have any power to fight back, they were more interested in the grenades of the Guards.

Then he cheekily asked the Guards for a small number of grenades to prepare, and he was also enjoyable, trying some grenade feelings.

Anyway, these grenades were originally specially fired for the existing long-barreled artillery of the army and navy, and in order to simplify logistics, the Tang Empire developed a unified caliber for the artillery of the army and navy.

Even in the actual production process, in order to make more efficient use of the existing production lines of the three major weapons companies, many of the artillery used by the army and navy are often different, that is, the gun carriages are different, but the barrels are basically the same.

The barrels used in the army's nine-pound field guns are actually no different from the navy's nine-pound naval guns, and they are even produced in the same production line.

Although the Guards are independent of the army and navy, their equipment is the same as that of the army and navy, after all, although they have their own system, they have not yet been forced to ask the Ministry of State-owned Enterprises to develop a complete set of weapons and equipment for them.

Strictly speaking, many of the weapons and equipment of the Guards are actually the same as those of the army and navy, and the artillery uses the army's standard standard artillery, and the flintlock pistol does not use the army's standard flintlock pistol, but uses the navy's flintlock pistol, which is characterized by a slightly shorter barrel than the army's standard rifle.

This also means that many weapons and equipment of the army, marines, and guards are actually the same, even if there are differences, but the difference is not big, and in terms of logistics, it is basically the same.

Shells, of course, are no exception.

After the Guards grenades were taken by the navy, because there were not many, there were only a few dozen rounds in total, and the second detachment of the navy was ready to take this opportunity to feel the power of the grenades in actual combat in advance.

So they randomly pulled a boat captured from the natives of Goryeo, opened their sails to keep the ship sailing, the personnel retreated, and then used it as a target ship!

It's just that although this scene looks like a real combat test, in fact, the people in the navy don't care about the problem of whether they can hit or not, because this is a problem of gunnery, and it is not much of a problem with artillery shells, they are more concerned about the effect of these grenades after hitting the target.

So in order to ensure the hit, they frantically drove the test battleship to a place less than 100 meters away from the target ship and opened fire!

Although it is said that in the battle on the sea, the low hit rate is scary, and the cannon is fired at a distance of more than 400 meters, so basically don't expect to have a high hit rate, but at this distance within 100 meters, as long as the gunner is not stupid, basically he will not miss!

In naval engagements, the engagements within 100 meters are basically already the stage of hand-to-hand combat with bayonets, and the hit rate is very high, and the competition is not about artillery skills, but about the number of artillery on both sides and the size of their power.

So a vote of admirals just stood on the bridge and stared at the target ship opposite!

With the sound of a cannon, they saw that the target ship on the opposite side, which was only a few tens of tons, suddenly rose into flames, because the distance was very close, they could clearly see the scene of sawdust flying after the shell exploded!

Another cannon rang out, this time the shell fell on the upper bridge at the stern of the ship, and the explosion also caused a violent wind and waves.

In the third shelling, they saw that the sails were all beaten to pieces.

The live-fire test continued, and they kept firing more than a dozen shots before stopping!

Although the hull of the ship is still intact as a whole, the upper deck and the interior are almost a mess, even the mast is broken, and the sail is even more porous, and it is impossible to continue sailing.

From a distance, the tattered ship was still floating on the sea, but everyone knew that if it was a real battle, this level of shelling would be enough to make the ship lose power and suffer heavy casualties.

After many naval officers personally boarded the target ship to see it, they couldn't help but have a scene in their minds: When the capital ships of the two sides faced off, the enemy could only stupidly shoot traditional shells such as solid shells, but they themselves sent grenades to the enemy's ships one after another, and the violent explosions destroyed their sails, killed and injured a large number of their personnel, and even caused the powder kegs on the enemy's ships to explode and catch fire.

When I thought of this kind of scene, it all made these naval officers excited: Our Datang Navy will be invincible in the world!
