I don't own this space under my name. I should have leased it while I still could

So it comes down to cost benefit. MAD is really only a confirmation aid where better aids might obviate the need for MAD. That said we once caught a submarine where MAD was the initial sensor. We were investigating a radar contact when we got a MAD mark. The JEZ buoy picked up noise, a second MAD was gained and the sub confirmed. Pure luck, but crews used to make their own luck.
