Could the shore-based Type 45 test installation defend its area?

Could the Type 45 test installation on the hill be used as a surface-to-air missile site?

It might provide useful protection for one area, but conversion would cost money and complicate the installation's testing and development role.

The question concerns the existing shore-based Type 45 test installation described as being on a hill. Turning it into an operational missile-defence site is considered possible, though it would cost money. It would protect only one area. Its continuing use for technology development and installation work would make an operational role more complicated. The qualified response is that some local protection would be useful, while the consequences for testing would have to be addressed.
