Described is an arrangement for supporting a circuit board (28) having functional components (30) on a carrier (16) of a projectile (10). The carrier (16) has a metal plate (18). The circuit board (28) comprises a carbon fibre-reinforced plastic material. Provided between the circuit board (28) and the metal carrier plate (18) is an elastic damping layer (26). The circuit board (28) and the damping layer (26)--like the metal carrier plate (18)--are spaced with their peripheral edges from the inside wall of the housing of the projectile (10).
