Defence Boom

Defence Boom.

This gateway to the River Thames was constructed in 1939. It consisted of wooden piles driven into the sands both sides of the Thames stretching to the edges of the deep water channel. Once the deep water channel was reached an anti-submarine net was placed across the remaining stretch of river. Stationed along the net there were large barges called lighters weighing some 200 tons. The boom was armed with anti-aircraft guns & searchlights, the purpose of the boom was to prevent enemy submarines from attacking anchored shipping in the river. It also prevented attack by enemy surface ships. The boom was dismantled after the war & all that remains today are the wooden piles with concrete reinforcing stretching out from East Beach Shoeburyness for just over 1 Kilometer into the Thames.
