Work will be performed at various locations including Huntsville, Alabama, with an initial delivery order valued at five hundred dollars issued on the award date under firm fixed price terms. The contract structure accommodates both classified and unclassified programs requiring appropriate facility clearances, positioning it as a strategic long-term investment supporting the nation's homeland and force protection objectives.
