STK 8, released fall 2006, focuses primarily on enhanced analysis collaboration and geospatial layer management, and also introduces the full integration of its 3-D visualization capabilities across a simplified product alignment structure. New features include the ability to easily manage globes and geospatial layers (including ArcGIS data); terrain and imagery processing improvements; enhanced analysis sharing capabilities, and more.

STK 7 debuted in fall 2005. This release included new features—Aircraft Mission Modeler, backwards targeting, custom missile creation tool, industry-standard COM interface—and across-the-board enhancements for users working in battlespace management, geospatial intelligence, space systems, and national defense.

STK 6.0 was launched in 2004. This software version gave users new and improved tools ideal for specialized analyses, terrain, and imagery handling; 3-D interactivity; and shareability.

The 2003 release of STK 5.0 brought an entirely new look and feel to STK via an updated graphical user interface (GUI). It's open architecture offered unparalleled flexibility to create custom interfaces and easily integrate STK with other software applications.

In 2002, STK 4.3 introduced the Vector Geometry Tool in STK/Professional (STK/PRO). Its dynamic geometry engine enabled the incorporation of time-based position, velocity, orientation, and inter-visibility conditions for objects—with respect to any coordinate system.
