A fin assembly includes a fin base, a fin tip rotatably connected with the fin base, and means for selectively locking the fin tip in a chosen configuration. A vehicle includes a body defining a cavity therein and defining an opening through a wall thereof, a fin control mechanism disposed within the cavity, and a fin base having an axle extending through the opening and engaged with the fin control mechanism. The vehicle further comprises a fin tip rotatably connected with the fin base, and means for selectively locking the fin tip in a chosen configuration. A method for configuring a fin assembly on a vehicle includes providing a fin tip rotatably connected with a fin base being operably coupled with the vehicle and selectively locking the fin tip in a first position relative to the fin base.

What is claimed is: 1. A fin assembly, comprising: a fin base having an axle configured to extend through an opening of a vehicle; a fin tip rotatably connected with the fin base; and means for selectively locking the fin tip in a chosen configuration, wherein the means for selectively locking the
What is claimed is: 1. A fin assembly, comprising: a fin base having an axle configured to extend through an opening of a vehicle; a fin tip rotatably connected with the fin base; and means for selectively locking the fin tip in a chosen configuration, wherein the means for selectively locking the fin tip further comprises a locking rod selectively engageable with the fin tip and an actuator for disengaging the locking rod from the fin tip. 2. A fin assembly, according to claim 1, wherein the means for selectively locking the fin tip further comprises an explosive squib for driving the actuator. 3. A fin assembly, according to claim 1, wherein the means for selectively locking the fin tip further comprises a fluid source and the actuator further comprises: a case having a cylinder wall and defining a cylinder therein in fluid communication with the fluid source; and a piston slidably disposed within the cylinder and including a head, such that, as fluid is introduced into the cylinder between the head and the cylinder wall, the piston engages the locking rod to disengage the locking rod from the fin tip. 4. A fin assembly, according to claim 1, wherein the means for selectively locking the fin tip further comprises a fluid source and a pad attached to the locking rod, wherein the actuator further comprises: a case having a cylinder wall and defining a cylinder therein in fluid communication with the fluid source; and a piston slidably disposed within the cylinder and including a head, such that, as fluid is introduced into the cylinder between the head and the cylinder wall, the piston engages the pad to disengage the locking rod from the fin tip. 5. A fin assembly, comprising: a fin base having an axle configured to extend through an opening of a vehicle; a fin tip rotatably connected with the fin base; and a selectively operable lock operably coupled to the fin base and the fin tip, and capable of locking the fin assembly in a chosen configuration, wherein the selectively operable lock comprises a locking rod selectively engageable with the fin tip and an actuator for disengaging the locking rod from the fin tip. 6. A fin assembly, according to claim 5, wherein the selectively operable lock further comprises an explosive squib for driving the actuator. 7. A fin assembly, according to claim 5, wherein the selectively operable lock further comprises a fluid source and the actuator further comprises: a case having a cylinder wall and defining a cylinder therein in fluid communication with the fluid source; and a piston slidably disposed within the cylinder and including a head, such that, as fluid is introduced into the cylinder between the head and the cylinder wall, the piston engages the locking rod to disengage the locking rod from the fin tip. 8. A fin assembly, according to claim 5, wherein the selectively operable lock further comprises a fluid source and a pad attached to the locking rod, wherein the actuator further comprises: a case having a cylinder wall and defining a cylinder therein in fluid communication with the fluid source; and a piston slidably disposed within the cylinder and including a head, such that, as fluid is introduced into the cylinder between the head and the cylinder wall, the piston engages the pad to disengage the locking rod from the fin tip. 9. A vehicle, comprising: a body defining a cavity therein and defining an opening through a wall thereof; a fin control mechanism disposed within the cavity; a fin base having an axle extending through the opening and engaged with the fin control mechanism; a fin tip rotatably connected with the fin base; means for selectively locking the fin tip in a chosen configuration; and means for urging the fin tip from a folded configuration into an unfolded configuration, wherein the means for selectively locking the fin tip further comprises a locking rod selectively engageable with the fin tip and an actuator for disengaging the locking rod from the fin tip. 10. A vehicle, according to claim 9, wherein the means for selectively locking the fin tip further comprises an explosive squib for driving the actuator. 11. A vehicle, according to claim 9, wherein the means for selectively locking the fin tip further comprises a fluid source and the actuator further comprises: a case having a cylinder wall and defining a cylinder therein in fluid communication with the fluid source; and a piston slidably disposed within the cylinder and including a head, such that, as fluid is introduced into the cylinder between the head and the cylinder wall, the piston engages the locking rod to disengage the locking rod from the fin tip. 12. A vehicle, according to claim 9, wherein the means for selectively locking the fin tip further comprises a fluid source and a pad attached to the locking rod, wherein the actuator further comprises: a case having a cylinder wall and defining a cylinder therein in fluid communication with the fluid source; and a piston slidably disposed within the cylinder and including a head, such that, as fluid is introduced into the cylinder between the head and the cylinder wall, the piston engages the pad to disengage the locking rod from the fin tip. 13. A method for configuring a fin assembly on a vehicle, comprising: providing a fin tip rotatably connected with a fin base, the fin base having an axle extending through an opening of the vehicle; selectively locking the fin tip in a first position relative to the fin base; selectively unlocking the fin tip; and rotating the fin tip to a second position relative to the fin base, wherein selectively unlocking the fin tip further comprises selectively disengaging a locking rod from the fin tip. 14. A method, according to claim 13, wherein selectively unlocking the fin tip further comprises driving an actuator to selectively disengage the locking rod from the fin tip. 15. A method, according to claim 14, wherein driving the actuator further comprises firing an explosive squib to drive the actuator. 16. A method, according to claim 14, wherein selectively unlocking the fin tip further comprises: introducing a fluid into a piston-type actuator; and engaging a portion of the actuator with a pad of the locking rod. 17. An apparatus, comprising: a fin tip rotatably connected with a fin base, the fin base having an axle extending through an opening of a vehicle; means for selectively locking the fin tip in a first position relative to the fin base; means for selectively unlocking the fin tip; and means for rotating the fin tip to a second position relative to the fin base, wherein the means for selectively unlocking the fin tip further comprises means for selectively disengaging a locking rod from the fin tip. 18.
