The category 6.2 situation is encouraging, but levels throughout this period have strained the Navy's ability to transition research to applications without resorting to the use of ship construction, Navy (SCN) funds to solve technology problems. This situation has been exacerbated by substantial declines in SCN budgets over the same period, as shown in Figure 2.2. Historically, technology development and technical solutions to fleet problems have been helped along with contributions from SCN funding. Not only is the lower SCN level a problem, but also as new ship classes become less frequent, an unstable profile results. This is not conducive to long-term research and technology goals, which benefit most from stable, well-planned technical efforts. Therefore, it is essential to have a critical mass of stable 6.1 and 6.2 funding.
