This paper addresses the problem of experimental reproducibility in the study of blast effects during explosive tactical breaching. In real conditions, breaching charges exhibit significant variability, which complicates the comparison of measured pressure responses and limits systematic research. The study investigates whether real breaching charges can be replaced by standardized spherical charges with an equivalent TNT effect. Experimental measurements were carried out in a training facility using pressure sensors, and the results were evaluated in terms of peak overpressure, impulse, and pressure-time history. The findings indicate that standardized charges provide comparable blast characteristics, with differences within acceptable limits. The proposed approach enables more reproducible experiments and creates a basis for further research on structural resilience and human exposure to repeated blast loading.

Using of 3D printed spare parts for Navy supply supported by mentioned inspection meets the requirement for enhancing the logistic performance by provide to military end-users possibilities to produce spare parts using additive manufacturing solutions, particularly in the context of overseas operations, that can be easily presented with several examples. But with application of additive manufacturing in naval operations to product different objects in a variety of materials in an open water environment, we need to start with development of innovative solutions for intelligent inspection of products of selective laser melting from metallic powders is a topic of great importance in nowadays if we talk about real strategies in logistic support including overseas naval outposts support equipment and the reverse engineering of obsolescent parts such as many of those that could be found on the perspective sea platforms with particular focus on maritime littoral and high sea areas—demonstrate advantages of additive manufacturing.
