(CNN)Ever wondered how to keep suspected Russian submarines out of your territorial waters?
Never mind expensive naval hardware -- Swedish peace activists have come up with a novel method: lowering a "Singing Sailor" device emitting a gay-friendly message via Morse code into the Baltic Sea.
The unlikely sounding device is the brainchild of the Swedish Peace and Arbitration Society, which describes itself as the world's oldest peace organization.
In an effort to combat military aggression and homophobia in one fell swoop, it's created the "subsurface sonar system" to greet any Russian submariners who might find themselves lost in Swedish waters.
The animated neon sign shows a man wearing only a sailor's hat and white underpants thrusting his hips, with little love hearts flashing. It bears the message: "Welcome to Sweden" in both Russian and English, with the text "Gay since 1944" -- a reference to the year that Sweden legalized homosexuality -- added in English.
A Morse code message simultaneously calls out: "This way if you are gay."
Sweden is working close with NATO so they would have all the NATO countries pointing their missiles at Russia at the same time if Russia tried anything.
