For those of you still worried about sample sizes for the OP's data, here are the corresponding post hoc Power Analyses:

Science Consoles
Effect Size = 1.118
alpha = 0.000213532
Sample Size = 131
df = 9
Power (1-beta) = 1.000

Engineering Consoles (I had to put in an observed probability of 1x10^-8 for the consoles the OP did not obtain)
Effect Size = 1632.99
alpha = 4.36x10^-22
Sample Size = 94
df = 14
Power (1-beta) = 1.000

Tactical Consoles (I had to put in an observed probability of 1x10^-8 for the consoles the OP did not obtain)
Effect Size = 883.88
alpha = 1.69^10-9
Sample Size = 88
df = 15
Power (1-beta) = 1.000

All three tests have sufficient sample sizes to determine the observed effect sizes.
