The effects of random dilution of junctions on a two-dimensionalJosephson-junction array in a magnetic field are considered. For rationalvalues of the average flux quantum per plaquette $f$, the superconductingtransition temperature vanishes, for increasing dilution, at a critical value$x_S(f)$, while the vortex ordering remains stable up to $x_{VL}>x_S$, muchbelow the value $x_p$ corresponding to the geometric percolation threshold. For$ x_{VL}<x<x_p$, the array behaves as a zero-temperature vortex-glass.Numerical results for $f=1/2$ from defect energy calculations are presentedwhich are consistent with this scenario.Comment: 4 pages, 4 figures, to appear in Phys. Rev.
