不久后，东方航天港应运而生。记者采访了解到，东方航天港的建设，也并非从无到有的"空中楼 阁"式构思，而是基于当地深厚的相关产业及科研基础。海阳所在的烟台，是工业大市、制造业强市， 这里既有万华化学等新材料龙头企业，又有蓝天钛金科技、华宇航天等航空航天代表项目，还有中科院 兰化所研究院等高校院所。另外，烟台拥有完备的整车、整机、整船制造产业体系，在机械、电控等制 造环节，与航天产业有很强的复用性，可就地转化为航天配套体系。 走进位于烟台海阳的东方航天港，从火箭制造车间前往海边发射场，一条长约6公里的航天大道， 由内陆向近海不断延伸，串起了沿途不同的功能区。在这里，卫星在"家门口"就能"搭上车"，火箭"走 几步"就能去发射，大大缩短了以往长达上千甚至上万公里的转运路程。 从首次海上发射任务成功，到如今航空航天链上企业超70家，东方航天港以海上发射为牵引，布局 发射链、火箭链、卫星链、文旅链，搭建了"天上有星、陆上有箭、海上有船、空中有网"的商业航天产 业体系。 有人说，海阳航空航天产业的发展简直是"无中生有"的发展。一个寂寂无闻的县级市，何以让"无 中生有"成为可能？ "无中生有"意味着在看似没有机会的地方发现并 ...
