Today on my way home from work, I saw an unknown 737 parked at the US military base in the south part of Stuttgart airport. It was already getting dark, and I didn't have a car with me to have a closer look, nor did I have binoculars with me, so I'm not even sure if it was a 737Classic or a 737NG (but it didn't have winglets). It was basically white, with a cheatline. As it was parked at the USAF base, I'm sure it was not a civil aircraft, but rather a US Air Force / Navy / Army aircraft. My suggestion would be a Navy 737-700:

But I'm not common with military used aircraft, so I might be wrong.
If CC32, B737-700, GeneralA or any other local STR spotters could even provide me with the registration, wow THAT would be great!
Thanks in advance!
