ILS Y Rwy 9?

[a-v-8er]

Has anyone seen an approach plate like this before that has the name of the approach as "ILS Y Rwy 9". What does the "Y" stand for?

The plate is part of the Jepp airway manual, but to a military airport. I don't have the plate here and don't know the name of the airport, but has anyone seen anything like this before? A letter being part of the approach name even when it has straigh-in-landing minimums...

Thanks for the info TonyC. I found the answer myself too, so here it is again if someone else is wondering...

The reason that they put the Y on the plate is that there is another ILS into the same runway. The history behind the Z, Y, X, W, etc is that on Alpha approaches, circling if there are more than one, the first is an A, the second is a B and so on. With other approaches, they name them starting at the other side of the alphabet to help eliminate confusion starting with the letter Z.
