If this is MUOS 4, then I expect it to drift/manoeuvre, untill it reaches 
longitude 75 East.

This are the current positions of earlier launched MUOS, based on Mike's INTTLES:

MUOS 1 near 178 W
MUOS 2 near 100 W
MUOS 3 near 17 W

There is an article, written by the lead MUOS developers, from Johns Hopkins APL 
Technical Digest 30:2 (2011):

http://www.jhuapl.edu/techdigest/TD/td3002/Oetting.pdf

...which depicts a constellation with MUOS satellites in slots at:

Pacific   177 W
CONUS     100 W
Atlantic  15.5 W
Indian    75 E
Spare     72 E

The first three slots (Pacific, CONUS, Atlantic) agree quite well with where we 
place MUOS 1 to 3: 178 resp. 177 W, 100 resp. 100 W, 17 resp. 15.5 W.

This leaves the slots at 75 E and 72 E.

So MUOS 4 most likely is destined for 75 E over the Indian Ocean.
