Tuhia he haere tonu mo tenei whitianga - I tohua a Dowling hei Knight Commander o te Order of the British Empire (KBE) i te 1957 New Year Honours, a ka oti tana wa hei CNS i te 23 o Hui-tanguru 1959. I te 23 o Poutu-te-rangi i riro ia i a Sir Henry Wells hei Tiamana o te Komiti Tiamana o nga Kaimahi (COSC), he mahi e tohu ana i te Tumuaki o te Rōpū Tiaki. I whai muri ia ia hei CNS e te Kaihauturu Admiral Henry Burrell. I miharo a Dowling i tana whakataunga hei Tiamana o te COSC, i tumanako ia ki te huri i te tuunga kia rite ai te mana whakahau ki nga rangatira o te ratonga, engari i tenei ka pouri ia. Ko te taumata o te tūranga i rite tonu ki nga upoko o te ope taua, Navy me te Air Force, a ko ia anake te kawenga mo te whakaatu i o raatau whakaaro mo nga take hoia ki te Minita mo te Parenga. Ko etahi atu ngoikoretanga i a ia e mahi ana ko te whakatau a te Tari Tiaki - i whakakorea i muri i tana wa - ki te whakakore i te Fleet Air Arm, me te kore o te kawanatanga o te kawanatanga ki te tautoko ia ia i tana panui i te huihuinga purongo a SEATO i te Poutu-te-rangi 1961 e rite ana a Ahitereiria ki te whakauru hoia i te raru tuarua o Laos.
ki te tika. I te marama o Hepetema 1959, i te wa o te raru tuatahi o Laotian, i whakamanahia e te kawanatanga o Ahitereiria a Dowling ki te tuku "he roopu hoia, he roopu RAAF, rererangi rererangi, me nga kaipatu RAN e rua" hei tautoko i nga ope US me SEATO, engari kaore i uru mai.
