I believe it is indeed useless. What use is 5,000 non-phased shield points? PPB would disable this facility, and even regular weapons could destroy the shield fairly especially. (I won't even speak of the planetary bombs, these ones should destroy the shield in no time) The only use would be to protect your planets against a single raider, but that is a bit expensive for such a purpose. And it won't repel a bigger offensive.
