The nose of a Rockwell B-1B 'Lancer' includes small triangular fin control surfaces or vanes. The B-1's Structural Mode Control System rotates the vanes automatically to counteract turbulence and smooth out the ride.
Also aiding the B-1's survivability is its relatively low radar cross-section (RCS). Although not technically a stealth aircraft in a comprehensive sense, thanks to the aircraft's structure, serpentine intake paths and use of radar-absorbent material its RCS is about 1/50th of the similar sized B-52's RCS; roughly equivalent to the RCS of a small fighter aircraft. -wiki
