This paper discusses an investigation into the utility of the Object Management Groups UML Profile for Schedulability, Performance, and Time RT-UML Profile for engineering a next generation of network centric, large-scale Command, Control, Intelligence, Surveillance, and Reconnaissance C2ISR aircraft. This activity applied the Profile in analysis of a multi-aircraft scenario, loosely based on DARPAs AMSTE research program. In this configuration, two aircraft, each with sensing capability, collaborate in real-time to develop precision targeting information for ground targets which is sent directly to in-flight munitions. This collaboration presents stressing, real-time requirements on a number of distributed, physically distinct platforms. The RT-UML Profile was used in conjunction with two commercial tools to perform analysis of the timing needs. Results of this activity indicate 1 the Profile assists engineers in developing better insight into temporal properties 2 the Profile fits well within the DoD development processes 3 use of sequence diagrams scales well for defining system load and 4 the Profile should more directly support threads that span software processes and physical resources.
