The posibility is very high that it is used as an enhancer of the shieldtechnology they are using. Best Example were the Stardestroyers, whose shield-generators were also added outside the ship's mainbody. (I think you can see that in Episode 6 in the spacefight near the 2nd Deathstar)
Well, but we just don't know enough about their technology and culture. For all we know it could just be sth religious/cultural by the designer of the shiptype.
(Or just a sick joke..)
