He said that the rockets for Flight 10 and Flight 11 are \u201cflowing through our production line\u201d and stated that they sold the majority of the company\u2019s 2027 launch manifest.<\/p>\n<p>Kim didn\u2019t name a specific number of launches planned for next year.<\/p>\n<figure id=\"attachment_72146\" aria-describedby=\"caption-attachment-72146\" style=\"width: 678px\" class=\"wp-caption alignnone\"><img decoding=\"async\" width=\"100%\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2026\/01\/20260113_firefly-alpha-block-i-vs-block-ii.jpg\"><figcaption id=\"caption-attachment-72146\" class=\"wp-caption-text\">A rendering of Firefly Aerospace\u2019s Alpha Block 1 rocket configuration compared to the Block 2 configuration.

The company said that it stemmed mainly from \u201ccosts related to the Alpha program associated with ramping production on our Alpha Block 2 configuration upgrade, stock-based compensation expense, depreciation and amortization from newly acquired assets being placed into service, and other R&amp;D initiatives.\u201d<\/p>\n<blockquote class=\"twitter-tweet\" data-media-max-width=\"560\">\n<p dir=\"ltr\" lang=\"en\">The next evolution of Alpha.<\/p>\n<p>Block II is the next-generation configuration of our Alpha rocket and the only operational U.S. 1-ton rocket.

Teams determined that increased thermal protection system thickness on the booster was needed after a rupture occurred following stage separation.<\/p>\n<p>The company also experienced an explosion of one of its Alpha boosters during an acceptance test at its facilities in Briggs, Texas, in late September.<\/p>\n<p>The Alpha Block 2 rocket is designed to overcome the issues that led to that explosion. That includes increasing the length of the vehicle by seven feet to account for larger liquid oxygen tanks; shifting to in-house manufactured batteries and avionics; and building stronger carbon composite structures.<\/p>\n<h4>Road to Eclipse<\/h4>\n<p>While progress continues towards the next version of its Alpha rocket, Firefly continues working towards bringing its medium-lift rocket, Eclipse, to life alongside Northrop Grumman. That rocket is now expected to debut sometime in 2027.<\/p>\n<p>\u201cWe are maturing Eclipse towards first flight. Our thunderous Miranda engine, designed for reusability, crossed 150 hot fire tests to date as the campaign crosses key milestones at pace,\u201d Kim said. \u201cA big, recent unlock was the flight-like mission duty cycle test that the team completed, with the engine firing for 226 seconds, all while completing both power ratio and mixture ratio sweeps.<\/p>\n<p>\u201cOur Miranda engine qualification test campaign is imminent, as our recent tests demonstrated the performance needed to meet the range of stress requirements during a launch.\u201d<\/p>\n<figure id=\"attachment_74140\" aria-describedby=\"caption-attachment-74140\" style=\"width: 678px\" class=\"wp-caption alignnone\"><img decoding=\"async\" width=\"100%\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2026\/08\/20260811_Firefly_Eclipse_rendering.jpg\"><figcaption id=\"caption-attachment-74140\" class=\"wp-caption-text\">An artist\u2019s interpretation of the launch of an Eclipse rocket, a launch vehicle being manufactured in partnership between Firefly Aerospace and Northrop Grumman.

That vehicle will use a solid rocket upper stage and is designed to fly up to three time to deliver Cygnus spacecraft to the International Space Station.<\/p>\n<p>Kim said that Firefly is \u201cfocused on delivering the vehicle\u2019s first stage\u201d to Northrop Grumman.
