With different markings. Willing to bet it is the same kit inside, typical MO for Minicraft. That being said...it is a nice kit, of a great aircraft in a reasonable size.
This is the modern H. I checked with scalehobbyist and they will be posting the new version this weekend.
represents the current, modern, flying model with antennas, electronic countermeasures and low light vision enhancements, postionable flaps and landing gear (up or down) and new decals representing 2 different B-52s currently in operation.
