Yep your missing something like I was above. Don't get any closer than 38nm as I was having the same trouble as you were.
If you get lit up by the Sam don't launch your JSOWS, turn around and wait till your out of its range then turn back and recommence.
If your having issues with gas, what I did was as soon as the bandits spawn in wait until they make a launch, fire your Ac's turn cold drop chaff and let the immortal wing man take care of them. In saying that I still needed to tank prior to turning for Mother.
Also try launching JSOWS as close to angels 40 as possible.
Cheers
