A stabilizing vane configured to mount to a projectile, the vane comprising: a generally flat base configured to mount to a surface of the projectile at a rearward end of the projectile, the base comprising: a longitudinal axis, an upper base surface, a lower base surface having a contour so as to match the surface of the projectile, a first base end and a second base end distal from the first base end along the longitudinal axis and an intermediate base portion extending there between, a first lateral side (23L1) and an opposing second lateral side (23L2) disposed on opposite sides of the longitudinal axis; and a semi-rigid ribbon strip comprising: a leading ribbon surface and a trailing ribbon surface, opposing first and second ribbon side edges (36E2, 36E1), and a first ribbon strip end and an opposing second ribbon strip end, with an intermediate ribbon strip portion extending rearward from the first ribbon end toward the second ribbon end, wherein the first ribbon strip end is attached to the upper base surface at the first base end, wherein the second strip end is attached to the upper base surface at the second base end, wherein the intermediate ribbon strip portion is spaced a distance from the intermediate base portion, wherein the ribbon strip is twisted such that the first ribbon side edge (36E2) faces forward adjacent the first ribbon end, faces laterally outward in the intermediate ribbon strip portion, and faces forward adjacent the second ribbon end, such that the ribbon strip is configured to induce spin to the projectile during flight of the projectile. a generally flat base configured to mount to a surface of the projectile at a rearward end of the projectile, the base comprising: a longitudinal axis, an upper base surface, a lower base surface having a contour so as to match the surface of the projectile, a first base end and a second base end distal from the first base end along the longitudinal axis and an intermediate base portion extending there between, a first lateral side (23L1) and an opposing second lateral side (23L2) disposed on opposite sides of the longitudinal axis; and a semi-rigid ribbon strip comprising: a leading ribbon surface and a trailing ribbon surface, opposing first and second ribbon side edges (36E2, 36E1), and a first ribbon strip end and an opposing second ribbon strip end, with an intermediate ribbon strip portion extending rearward from the first ribbon end toward the second ribbon end, a longitudinal axis, an upper base surface, a lower base surface having a contour so as to match the surface of the projectile, a first base end and a second base end distal from the first base end along the longitudinal axis and an intermediate base portion extending there between, a first lateral side (23L1) and an opposing second lateral side (23L2) disposed on opposite sides of the longitudinal axis; and a semi-rigid ribbon strip comprising: a leading ribbon surface and a trailing ribbon surface, opposing first and second ribbon side edges (36E2, 36E1), and a first ribbon strip end and an opposing second ribbon strip end, with an intermediate ribbon strip portion extending rearward from the first ribbon end toward the second ribbon end, a leading ribbon surface and a trailing ribbon surface, opposing first and second ribbon side edges (36E2, 36E1), and a first ribbon strip end and an opposing second ribbon strip end, with an intermediate ribbon strip portion extending rearward from the first ribbon end toward the second ribbon end, wherein the first ribbon strip end is attached to the upper base surface at the first base end, wherein the second strip end is attached to the upper base surface at the second base end, wherein the intermediate ribbon strip portion is spaced a distance from the intermediate base portion, wherein the ribbon strip is twisted such that the first ribbon side edge (36E2) faces forward adjacent the first ribbon end, faces laterally outward in the intermediate ribbon strip portion, and faces forward adjacent the second ribbon end, such that the ribbon strip is configured to induce spin to the projectile during flight of the projectile.
