Proton 4 (Proton-2 1 / N-6 #1)
Proton 4
The N-6 (a.k.a. Proton-2) was an improved version of the N-4 satellite. It was designed to study the interaction of elementary particles with energies in excess of 1012 eV up to 1015 eV. Due to the instrumentation, the N-6 was much heavier than the N-4. Of it's mass of 17 t, 12.5 t were scientific instrumentation, making the N-6 the heaviest scientific satellite up to this date. A second N-6 was never launched.
