I believe there was a place built underwater but it was a very small research base... It was nowhere as sophisticated as Orca and I don't believe there will ever be anything built like Orca... Unfortunatley we live in the world of money and there is definitley no likely way to accomplish Orca's goal and make money under the sea. Thus the ends do not make the means so, we don't get Orca... Sorry... Maybe in the Future.
