Synopsis

An air carrier flight crew reported a NMAC with a company jet during their initial climbout.

Narrative

Took off on Runway 25R. About 30 seconds after Takeoff Tower called out traffic 9 o'clock Aircraft X. I looked to my left and didn't see the traffic. At about 1200 feet AGL we got a TCAS RA (Resolution Advisory) 'MONITOR VERTICAL SPEED'. I looked at the PFD (Primary Flight Display) and saw that I was in the 'CRITICAL' and I needed to increase my pitch to stay out of the 'CRITICAL'. The First Officer told me he saw '-100 in the nav display and it was right off the nose. It was close; really close. He told me that he was reducing the range to get an idea exactly where it was. It took about 20 seconds for the 'CLEAR OF CONFLICT' aural to annunciate. We told Tower that we responded to an RA. The only thing I would have done differently was to command Continuous Climb and/or pushed the power up. I don't understand how Tower could have allowed traffic so close to the departure corridor at the altitude Aircraft X was at. I would like to know how close Aircraft X came to my aircraft.I feel that PHX tower was responsible for the near miss. The Tower did not command Aircraft X to turn; descend. It seemed like the Tower Controller lost situational awareness.The planned weight of the takeoff was 170.2 thousand pounds. We were as heavy and slow as we would be until touchdown. If something like this occurs again I will tell Tower to please ensure separation.

Second reporter narrative

Around 30 seconds after rotation; climbing through 1300AGL Tower called out traffic 9 o'clock Aircraft X 'should be turning eastbound'. I responded with 'searching' but we were nose up and climbing so couldn't acquire traffic and in a phase of flight where our primary focus is safely climbing away from the airport and retracting flaps. Passing about 1600AGL we received a 'monitor vertical speed' Resolution Advisory with climb indications. The Captain; who was Pilot Flying complied and while analyzing the situation I noticed the conflict as displayed was right off the nose indicating -01 in critical zone with neither a climb nor descent symbology. I scaled down my display to gain better situational awareness on the conflict's relative distance; saw a small gap and then crosschecked the PFD (Primary Flight Display) to ensure we were still complying with the climb command and at that time heard 'clear of conflict'. I relayed what had happened to ATC and we safely retracted flaps and continued on the departure. Air Traffic Control not creating enough distance between local traffic and the departure corridor.No need to let traffic operate in that tight of a vicinity. Our takeoff clearance could have been delayed 15 seconds or Aircraft X not vectored so close to the corridor.
