Defense projects are often very costly and require high technology. The complexity of the requirements that arise while defining the system can sometimes cause the project to exceed the projected budget, sometimes lead to a very long duration and sometimes completely cancellation of the project. Failure to take the needed defense system into inventory when needed may cause the system to become outdated and no longer a necessity. Countries that are pioneers in the development of defense systems are more exposed to technology capability risk, while countries that replicate existing systems are less exposed to this risk. Although the USA, which is the leading country in the development of defense projects, spends billions of dollars, it sometimes may cancel some defense projects or reduce the initial supply considerably due to the problems it faces. In fact, countries such as Russia and China may cancel many defense projects they have started. However, the non-transparent structures of these countries and the fact that they carry out projects with a high level of confidentiality limit access to information. For this reason, two projects that were canceled even though billions of dollars were spent in the USA were selected and the reasons for the cancellation of these projects were analyzed with the case study method. In the study, the relationship between technology readiness level and project success is examined. Document analysis is used as a data collection technique and chronological order is followed.
