Projectiles containing a fluorophore composition comprising a fluorophore compound and an activator composition comprising an activator compound for marking targets are disclosed. Some embodiments include a nose structure with a cavity radially segmented into a plurality of radially isolated compartments by at least one laterally and radially extending internal wall. Additional embodiments include a fore compartment and an aft compartment sealed by a septum. Yet additional embodiments include at least one pressurized cavity and may further include a plunger positioned and configured to pierce each pressurized cavity. Methods of manufacturing target marking projectiles and methods of marking targets are also disclosed.

1. A projectile, comprising: a payload body comprising a nose structure defining a fore compartment therein;a cup structure defining an aft compartment therein;a septum sealing the aft compartment of the cup structure from the fore compartment of the nose structure; andat least one longitudinally and radially extending baffle within at least one of the fore and aft compartments,wherein one of the fore and aft compartments contains a fluorophore composition and the other of the fore and aft compartments contains an activator composition. 2. The projectile of claim 1, wherein the septum is configured to fracture upon launch of the projectile and prior to impact with a target. 3. The projectile of claim 1, wherein the septum is configured to fracture upon impact of the projectile with a target. 4. The projectile of claim 1, wherein: the nose structure comprises a polymeric nose structure;the cup comprises a metallic cup; andthe septum comprises a metallic disc. 5. The projectile of claim 1, wherein the fluorophore composition and the activator composition are formulated, upon combination, to react to emit light within the visible light spectrum. 6. The projectile of claim 1, wherein the fluorophore compound and activator compound are formulated, upon combination, to react to emit light within the near infrared light spectrum. 7. The projectile of claim 1, wherein the projectile is sized and configured as a 40 mm diameter ordnance round. 8. The projectile of claim 1, further comprising a rotating ring on an exterior of at least one of the nose structure and the cup structure. 9. The projectile of claim 1, comprising a plurality of score lines on an exterior of the nose structure. 10. The projectile of claim 1, wherein the fluorophore composition comprises 1,4,8,11,15,18,22,25-octabutoxy-29H,31H-phthalocyanine, an oxalate compound and at least one phthalate compound. 11. The projectile of claim 1, wherein the activator composition comprises hydrogen peroxide, a sodium phosphate, polyethylene glycol, water, tert-butanol, a luminescent catalyst system, and at least one phthalate compound. 12. The projectile of claim 1, wherein the fluorophore composition comprises 1,8-dichloro-9,10-bis(phenyl-ethynyl)anthracene, bis(2,4,5-trichloro-6-carbopentoxyphenyl)oxalate, and at least one phthalate compound. 13. The projectile of claim 12, wherein the activator composition comprises hydrogen peroxide, a sodium phosphate, polyethylene glycol, water, tent-butanol, a luminescent catalyst system, and at least one phthalate compound. 14. A method of manufacturing a projectile, the method comprising: forming a nose structure comprising a fore compartment, the fore compartment containing a fluorophore composition comprising a fluorophore compound or an activator composition comprising an activator compound;forming a cup structure comprising an aft compartment, the aft compartment containing the other of the fluorophore composition comprising the fluorophore compound or the activator composition comprising the activator compound;forming at least one longitudinally and radially extending baffle within at least one of the fore and aft compartments; andseparating the fore compartment and the aft compartment with a septum. 15. The method of claim 14, further comprising configuring the septum to fracture upon launch of the projectile and prior to impact with a target. 16. The method of claim 15, wherein configuring the septum to fracture upon launch of the projectile and prior to impact with the target comprises forming at least one of score lines, grooves, weakened portions, and thinned portions on the septum. 17. The method of claim 14, further comprising configuring the septum to fracture upon impact of the projectile with a target. 18. The method of claim 14, wherein separating the fore compartment and the aft compartment with the septum comprises forming a seal between the fore compartment and the aft compartment. 19. The method of claim 14, further comprising sealing the nose structure to the cup structure.
