Narrative:

The airspace described above is the normal descent and vectoring area for crp approach for approachs to runway 13. This airspace is also used by the navy as a training/transition area. The navy does not communicate with crp approach. The near miss occurred as we descended for an approach to runway 13R. Approach called out traffic at 1 O'clock and 12 mi. We did not see the traffic for a few seconds. When we saw the traffic (2 aircraft with one flying below and behind the other), my first officer increased our rate of descent to go under the high aircraft which was the greatest threat. The high aircraft went over us and the low aircraft went under us. My first officer also began a left turn but the increased descent is what prevented a probable collision. My feeling is that the aircraft were navy trainers who frequent the area. There needs to be an increased cooperation between crp approach and the navy to prevent future occurrences.

Title: CLOSE PROX ACR-MLG 2-MTR'S.

Narrative: THE AIRSPACE DESCRIBED ABOVE IS THE NORMAL DSCNT AND VECTORING AREA FOR CRP APCH FOR APCHS TO RWY 13. THIS AIRSPACE IS ALSO USED BY THE NAVY AS A TRNING/TRANSITION AREA. THE NAVY DOES NOT COMMUNICATE WITH CRP APCH. THE NEAR MISS OCCURRED AS WE DSNDED FOR AN APCH TO RWY 13R. APCH CALLED OUT TFC AT 1 O'CLOCK AND 12 MI. WE DID NOT SEE THE TFC FOR A FEW SECS. WHEN WE SAW THE TFC (2 ACFT WITH ONE FLYING BELOW AND BEHIND THE OTHER), MY F/O INCREASED OUR RATE OF DSCNT TO GO UNDER THE HIGH ACFT WHICH WAS THE GREATEST THREAT. THE HIGH ACFT WENT OVER US AND THE LOW ACFT WENT UNDER US. MY F/O ALSO BEGAN A LEFT TURN BUT THE INCREASED DSCNT IS WHAT PREVENTED A PROBABLE COLLISION. MY FEELING IS THAT THE ACFT WERE NAVY TRAINERS WHO FREQUENT THE AREA. THERE NEEDS TO BE AN INCREASED COOPERATION BTWN CRP APCH AND THE NAVY TO PREVENT FUTURE OCCURRENCES.
