Multi-Year Plan Poseidon: Jerusalem’s Doctrine for Israeli Navy Superiority to Counter Mavi Vatan.
👇 A maritime doctrine |
@IsraelHayomEng
The Air Force remains Israel’s spear: fast, precise, deep, decisive. Nothing replaces it.
But Israel’s next depth is not in the sky.
It is at sea.
Through the Mediterranean run Israel’s lifelines: trade, gas, communications, Europe and the world. The Red Sea is the second gate. Together they form Israel’s maritime perimeter.
The Navy did not wait for doctrine. It guarded the coast, blocked Gaza infiltration, secured offshore gas, sustained the submarine arm, supported operations ashore and extended south when the threat moved.
The old mission did not fail.
It ended.
Now comes sea power.
Israel is becoming an air-and-sea power. The Navy must rise to the scale, priority, prestige, industry and reputation of the Air Force.
Not its copy.
Its equal.
Ankara is manufacturing a Turkish perimeter at sea: Mavi Vatan, shipyards, drone carriers, submarines, frigates, planned destroyers, missiles, ports, exercises and forward partnerships.
From the Aegean and Cyprus through Libya and the Red Sea, from the Bosporus to the Horn of Africa, Turkey is turning water into leverage.
The Turkey-Libya maritime fiction is not a Greek paperwork dispute. It touches Israel’s sea lanes, cables, gas and Mediterranean gate. Israel has gone to war before when others tried to close its sea gates.
The Turkish occupation of northern Cyprus is no longer only a Cypriot problem. Once the occupied north becomes an operational threat to Israel, it becomes an Israeli problem.
Not a frozen conflict.
A forward platform.
Poseidon’s Wrath is the contingency inside the doctrine: neutralize the threat, help restore Cypriot sovereignty over territory taken by force, and hold the theatre after the strike.
That is the threshold.
The MYP is Zebulun.
In its Mediterranean register, it is Poseidon.
Zebulun is Israel’s Hebrew return to the sea. Poseidon is the Mediterranean name of the mission.
Three phases.
Nachshon: entry. Sa’ar 6, Naval Iron Dome, gas-rig defence, Red Sea posture and maritime air defence. The missing step is hierarchy.
Tannin: depth. Submarines, sensors, UUVs, acoustic intelligence, mine detection, ASW, cable protection and covert endurance. Not platforms. Undersea architecture.
Tarshish: horizon. Range, logistics, naval aviation, drone motherships, maintenance depth, permanent Red Sea and eastern Mediterranean posture, larger platforms, undersea networks, exportable Israeli naval systems and an officer corps whose prestige matches the mission.
No supercarrier.
An Israeli projection platform: smaller, smarter, uncrewed-heavy, modular, networked, harder to neutralize.
The budget is doctrine in numbers: NIS 80-120 billion over a decade.
Platforms, submarines, USVs, UUVs, munitions, shipyards, simulators, training, maintenance, undersea infrastructure, southern posture and Mediterranean endurance.
Not excess.
Overdue.
The procurement logic is sovereignty, not shopping.
Israel buys steel, tonnage and shipyard capacity from trusted partners.
It does not outsource the brain: C4I, radars, missiles, air defence, EW, cyber, sensors, data links and combat integration.
The United States remains essential.
It is not the gatekeeper of this file.
In the eastern Mediterranean, Washington balances contradictions Israel cannot inherit: Turkey, NATO cohesion, Black Sea access, Gulf interests and de-escalation.
On this file, Israel belongs with Europe’s waterline states - Greece, Cyprus and France - not America’s alliance-management instinct.
The Navy’s offensive mission is sea-denial, strike and A2/AD.
It no longer merely guards Israel from the sea.
It denies the enemy the sea against Israel.
The Air Force strikes beyond Israel’s borders.
Sea power holds beyond Israel’s shores.
For a state whose most important gate to the world is the sea, this is not ambition.
It is doctrine in motion.
