As an AI developed by OpenAI, I can provide some information on the possible procedures undertaken when trying to analyze fragments of a nuclear-capable missile.
Analyzing fragments of a missile, especially one capable of carrying nuclear warheads, mainly involves various scientific processes. Here are a few key points:
1. **Material Analysis**: The fragments would go through several stringent scientific tests aiming at identifying the type of materials used in the manufacture of the missile. Different nations use different building materials and technologies, offering a clue to the origin of the missile.
2. **Technological Assessment**: The technology used to design and build the missile also holds significant information. The ballistic technology, guidance systems, propulsion systems, and overall structural design are crucial factors that analysts would investigate.
3. **Chemical Analysis**: Nuclear missiles utilize radioactive materials, and the residue in the missile fragments can indicate the presence of such substances. Specialized equipment can detect minute traces of radioactive materials.
4. **Warhead Analysis**: If fragments are from the warhead portion of the missile and any radioactive material is found, this would be proof that the missile was capable of carrying a nuclear payload.
5. **Forensic Analysis**: The patterns of damage on the missile fragments can reveal information about how it was fired, its flight path, and its detonation.
Please note that this is a simplified explanation. The actual process is very complex and would be conducted by highly trained specialists in a controlled environment ensuring everyone’s safety from potential radiation or
