المركزية كبديلين محتملين للوكهيد أ -12 وس ر-71 في منتصف الستينات. اُعتبر الاقتراح الأول المسمى إسنجلاس، طائرة تحلق على المرتفعات العالية بسرعة 4ماخ- 5ماخ (4,900-6125 كم/ساعة؛ 3045-3806 ميل/ساعة)، تطورًا غير كافٍ على الطائرات الموجودة حاليًا. أما الاقتراح الثاني فهم تصميم أكثر تقدمًا بكثير يشار إليه أحيانا بمشروع رينبيري وكان يُطلق من الجو، بسرعة 20ماخ (24500 كم / ساعة؛ 15220 ميل في الساعة) الطائرات التي تعمل بالطاقة الصاروخية الانشطارية التي كانت ستستخدم مسارًا مرتفعًا جدًا لتجنب الدفاعات. اُعتبرت هذه الطائرة مكلفة للغاية وتم التخلي عن المشروع عام 1967.</span><small>

by the Central Intelligence Agency (CIA) as potential replacements for the Lockheed A-12 and SR-71 during the mid-1960s. The first proposal under the Isinglass name, a high-altitude plane to fly at Mach 4 – Mach 5 (4,900–6,100 km/h; 3,000–3,800 mph), was considered an insufficient advancement over existing aircraft; the second, much more advanced design, sometimes referred to as Project Rheinberry, was an air-launched, Mach 20 (24,500 km/h; 15,200 mph) rocket-powered boost-glide aircraft that would use a very-high-altitude trajectory to avoid defenses. This aircraft was considered too costly for development, and the project was abandoned in 1967.</span><small> (en)</small></span></li> <li style="display:none;"><span class="literal"><span property="rdfs:comment" lang="pt" >Projeto Isinglass era o codinome dado a duas aeronaves de reconhecimento, estudadas pela Agência Central de Inteligência (CIA) como potenciais substitutos para o Lockheed A-12 e o SR-71 em meados da década de 1960.
