Naval Warfare in Frontkrieg: Fleets, Landings & Sea Control

Naval warfare in Frontkrieg is the fight to control the sea zones that link continents, feed your economy, and open the door to surprise landings deep behind enemy lines. Whoever rules the sea decides where and when the next battle begins. In this free browser strategy game about World War 1, with a map of 4,800 provinces and matches of up to 500 players, your fleet matters just as much as your land army. This guide is for players who already know the basics and want to master surface ships, submarines, and amphibious landings to win where land-only opponents cannot reach. Below you will find the roles of naval forces, sea-zone control tactics, a step-by-step landing plan, and a lesson from the Battle of Jutland you can apply right now.

What naval warfare means in Frontkrieg

The map is split into land provinces and sea provinces. Sea zones are not empty space between coasts — they are a separate theater of war: the shortest routes between regions run through them, convoys are intercepted there, and this is exactly where surprise landings come from. A player who ignores the sea hands half the map to the enemy for free.

The core idea is simple: land gives you resources and infantry, while the sea gives you mobility and surprise. A fleet lets you move an army overnight to a spot that a land march would take several days to reach, striking an undefended coast while your opponent has committed everything to the main front.

Naval unit types and their roles

Naval forces in Frontkrieg handle three different jobs. Confusing them is a classic beginner mistake — building one ship type and then wondering why you keep losing at sea.

Surface fleet

Cruisers and battleships are the fist of your navy. They dominate the open sea, sink enemy ships, and bombard coastal provinces from range without stepping into shore-battery fire. Keep surface ships in a group (a stack): a lone battleship is easy prey, while a squadron of several ships controls an entire sea zone and survives incoming fire.

Submarines

Submarines are the eyes and the ambush of your navy. They move hidden, lift the fog of war over sea routes, and strike enemy convoys by surprise. A submarine will lose a straight fight against a large squadron, so use it as a scout and a hunter of lone targets, not as a capital ship in a decisive battle.

Transports and amphibious landings

Any land army can put to sea, but it is slow and vulnerable on the way. That is why landings always travel with warships: your surface fleet escorts the transport armies while they cross the zone. Without an escort your infantry risks going to the bottom before it ever sees the enemy shore.

Sea-zone control: why it wins games

Controlling a sea zone gives you three things at once: safe passage for your own armies, a blockade of enemy routes, and protection for your trade and resource lanes. In a match where up to 70 AI nations and hundreds of live players fight at once, whoever holds the key straits effectively collects a "tax" from every neighbor.

A practical rule: do not try to control the whole ocean. Pick 2–3 narrow zones — straits, sea entrances, approaches to islands — and keep permanent squadrons there. This is cheaper than spreading your fleet across the map and delivers a bigger strategic payoff for the same money.

Amphibious landings: how to put an army ashore, step by step

The landing is the most powerful tool in naval warfare because it moves the front into the enemy's undefended rear. Do it in this order:

• Step 1. Gather a strike army on a coastal province where the crossing will begin.
• Step 2. Form an escort squadron of surface ships and, if possible, a submarine scout out front.
• Step 3. Send the battle fleet into the target sea zone first to clear it of enemy ships.
• Step 4. Move the transport army along the same route under the fleet's cover, never blind.
• Step 5. Land on a lightly defended coast, not head-on into a fortified capital.

The best landing targets are untouched industrial regions, islands, and the rear of an enemy who has pulled every unit up to the land border.

Coastal defense: how to meet an enemy landing

Naval warfare is not only about attacking. If you have a long coastline, the enemy will sooner or later try to land in your rear. Three simple habits save you from a surprise landing.

• Keep a patrol submarine in the neighboring sea zone — it will warn you of an approaching fleet through the fog of war.
• Do not leave coastal provinces bare: even one or two garrison units slow a landing down until your fleet arrives.
• Keep a mobile reserve in the center, not spread around the perimeter, so you can rush it to a breakthrough in a single move.

Remember: a transport army is most vulnerable while still at sea. It is far cheaper to intercept a landing with a squadron on the water than to dig the enemy out of a captured city later.

Bergen Island: the top naval prize

The map features a neutral sea-only island, Bergen, that yields roughly 10 times more oil and money than an ordinary province. You can only reach it by sea, so Bergen is a pure reward for ruling the water. Take it early, cover it with a squadron, and your economy gets the fuel for tanks and aircraft while rivals are still squabbling over land borders.

Bergen also works as a conflict magnet: fleets clash near it constantly, so keep a reserve nearby, ready to intercept an enemy landing or finish off a weakened squadron.

Lessons from the Battle of Jutland

The largest naval battle of World War 1 — the Battle of Jutland (31 May – 1 June 1916) — pitted about 250 ships against each other: 151 British against 99 German. The British lost 14 ships and more than 6,000 sailors, the Germans 11 ships and roughly 2,550 sailors. On paper the Germans sank more tonnage, but strategically they lost: the British blockade of the North Sea held, and the German fleet barely put to sea again for the rest of the war.

The lesson for Frontkrieg is direct: victory at sea is measured by zone control, not by ships sunk. You can lose more units in a trading battle and still win the match if the enemy fleet is bottled up in port while your landings roam freely. Play for the blockade, not for the kill count.

Frequently asked questions

Can you win a match with a land army only?

You can, but it is harder. On maps with islands and sea-split regions, a player without a fleet cannot reach a third of the objectives, including Bergen Island with its triple economy. A minimal fleet is almost always required.

Which is stronger — a battleship or a submarine?

In a straight fight the surface squadron wins. But the submarine is not built for a straight fight: its strength is stealth and surprise strikes on lone ships and transports. They are different tools for different jobs, not a "better" and a "worse" ship.

How do I protect a landing from being sunk?

Never send a transport army alone. Clear the sea zone with your battle fleet first, then move the army along the same route under escort. Land well away from enemy ports and shore batteries.

How much does it cost to play Frontkrieg?

Nothing. Frontkrieg is free, with no pay-to-win and no download — it runs right in your browser, with a fresh match every day.

Conclusion

Naval warfare in Frontkrieg decides matches just as much as fighting on land: it delivers mobility, surprise, and access to the richest prizes such as Bergen Island. Remember the one rule Jutland already proved: what matters is not the ships-sunk count but control of the key sea zones. Build a balanced fleet, hold the narrow straits, escort your landings — and the half of the map that land-only players fear becomes your trump card.
